Crystal structure of [1,3-bis-(2,4,6-tri-methyl-phen-yl)imidazolidin-2-yl-idene]di-chlorido-{2-[1-(di-methyl-amino)-eth-yl]benzyl-idene}ruthenium including an unknown solvate.

The title compound, [RuCl2(C21H26N2)(C11H15N)], is an example of a new generation of N,N-dialkyl metallocomplex ruthenium catalysts with an N→Ru coordination bond as part of a six-membered chelate ring. The Ru atom has an Addison τ parameter of 0.234, which indicates a geometry inter-mediate between square-based pyramidal and trigonal-bipyramidal. The complex shows the usual trans arrangement of the two chloride ligands, with Ru-Cl bond lengths of 2.3397 (8) and 2.3476 (8) Å, and a Cl-Ru- Cl angle of 157.47 (3)°. The crystal structure features C-H⋯Cl, C-H⋯π and π-π stacking inter-actions. The solvent mol-ecules were found to be highly disordered and their contribution to the scattering was removed with the SQUEEZE procedure in PLATON [Spek (2015). Acta Cryst. C71, 9-18], which indicated a solvent cavity of volume 1096 Å3 containing approximately 419 electrons. These solvent mol-ecules are not considered in the given chemical formula and other crystal data.

Chemical context

Since the 1980s metathesis has become an important industrial process, but applications of the first-generation catalysts to targets bearing various functional groups were often precluded by the dramatic increase of their catalytic activity (Delaude & Noels, 2005 ▸; Astruc, 2005 ▸). Hence, in recent years a large number of new catalysts have been proposed, developed and implemented in organic chemistry processes. These new catalysts may be used in the presence of various functional groups, moisture traces, in a wide range of solvents under different temperatures and for many metathesis reactions including CM (cross metathesis), ROM (ring-opening metathesis), RCM (ring-closing metathesis), ROMP (ring-opening metathesis polymerization), ADMET (acyclic diene metathesis polymerization) and others (Dragutan et al., 2005 ▸; Grubbs et al., 2015 ▸; Hoveyda & Zhugralin, 2007 ▸). Currently, the most widely used catalysts are ruthenium-based heterocyclic carbene-coordinated metallocomplexes, containing, as rule, a five-membered ruthenium-containing ring with an O→Ru coordination bond (the Hoveyda–Grubbs catalysts of the second generation) (Ogba et al., 2018 ▸; Samojłowicz & Grela, 2009 ▸; Vougioukalakis & Grubbs, 2010 ▸).

Currently, there is only scarce information about the synthesis and application in the metathesis reactions of the nitro­gen-containing Grubbs catalysts, where the oxygen atom is substituted by an N atom in a five-membered ring. The known compounds of that type have promising catalytic properties and are already used in the industry. For example, there is patent information that describes applications of such a type of catalysts in ring-opening metathesis polymerization reactions (Zheng-Yun, 2017 ▸; Xia, 2017 ▸; Zheng-Yun, 2011 ▸; Polyanskii et al., 2015 ▸; Ivin & Mol, 1997 ▸).

The purpose of this study is to elaborate the synthesis of new generation of N,N-dialkyl metallocomplex ruthenium catalysts, resulting in establishment of connection between the nature of the functional groups born by the nitro­gen atom and the catalytic activity and stability of these catalysts in various metathesis reactions as well as in the determination of the effect of substituents on the structures of the obtained products.

Structural commentary

The Ru atom in the title compound is penta­coordinated to two C, one N and two Cl atoms (Table 1 ▸). The Addison τ parameter is used to describe the distortion of the coordination geometry and is defined as τ = (difference between two largest angles/60) for five-coordinated metal centers, allowing the distinction between trigonal–bipyramidal (ideally τ = 1) and square-pyramidal (ideally τ = 0) geometries. For the title complex, τ = 0.234, in between these two geometries (Figs. 1 ▸ and 2 ▸). The dihedral angle between the planes of the tri­methyl­phenyl rings is 31.95 (19)°. The complex shows the usual trans arrangement of the two chloride ligands, with Ru—Cl bond lengths of 2.3397 (8) and 2.3476 (8) Å, and a Cl—Ru— Cl angle of 157.47 (3)°. The bond lengths and angles about the Ru atom are in good agreement with those in the di­chloro­methane solvate [(SPY-5-34)-di­chloro­(2-formyl­benzyl­idene-κ2-C,O)[1,3-bis­(2,4,6-tri­methyl­phen­yl)-4,5-di­hydro­imidazol-2-yl­idene]ruthenium] (Slugovc et al., 2004 ▸) and cis-di­chlorido­(1,3-dimesitylimidazolidin-2-yl­idene)(2-formyl­benzyl­idene-κ2 C,O)ruthenium diethyl ether solvate (Slugovc et al., 2010 ▸).

Both cis-di­chlorido­(1,3-dimesitylimidazolidin-2-yl­idene)(2-formyl­benzyl­idene-κ2 C,O)ruthenium diethyl ether solvate (Slugovc et al., 2010 ▸) and the di­chloro­methane solvate [(SPY-5-34)-di­chloro­(2-formyl­benzyl­idene-κ2 C,O)[1,3-bis­(2,4,6-tri­methyl­phen­yl)-4,5-di­hydro­imidazol-2-yl­idene]ruthenium] (Slugovc et al., 2004 ▸), show similar metal-atom geometries to the title compound. In contrast to the di­chloro­methane solvate, where the Ru complexes do not show any inter­molecular π–π-stacking but are linked by C—H⋯π and C—H⋯Cl inter­actions (Jlassi et al., 2014 ▸; Ma et al., 2017a ▸,b ▸; Shixaliyev et al., 2013 ▸, 2014 ▸, 2018 ▸), inter­molecular π–π stacking is an important factor in the crystal structures of the title complex and cis-di­chlorido­(1,3-dimesitylimidazolidin-2-yl­idene)(2-formyl­benzyl­idene-κ2 C,O)ruthenium diethyl ether solvate where these inter­actions form a framework-like structure containing channels that extend along the b and c axes, respectively. The crystal structures of some ruthenium-based heterocyclic carbene-coordinated metallo-complexes, containing a five-membered ruthenium-containing cycle with an O→Ru coordination bond have been reported by Samojłowicz et al. (2009 ▸).

Synthesis and crystallization

The synthesis of the title complex (5) was performed by the inter­action of the indenyl­idene derivative (1) with 1,3-dimes­ityl-2-(tri­chloro­meth­yl)imidazolidine (2). The inter­mediate (3), which is unstable in air, was not isolated and was directed to the following reaction step with styrene (4) as described earlier (Dorta et al., 2004 ▸; Fürstner et al., 2001 ▸; Jimenez et al., 2012 ▸; Pump et al., 2015 ▸) (Fig. 4 ▸). The catalyst (5) was obtained in moderate yield and turned out to be a green powder, stable in air at room temperature for at least four years.

Synthesis of the Hoveyda–Grubbs catalyst (5):

Absolute toluene (50 ml), di­chloro­(3-phenyl-1H-inden-1-yl­idene)bis­(tri­cyclo­hexyl­phosphane)ruthenate (1) (3.52 g, 3.81 mmol) and 1,3-bis­(2,4,6-tri­methyl­phen­yl)-2-tri­chloro­methyl­imidazolidine (2) (1.94 g, 4.56 mmol) were placed into a 100 ml Schlenk flask purged with argon. The mixture was heated under argon at 358 K for 5 h, then the mixture was cooled at room temperature and 1-(2-ethenylphen­yl)-N,N-di­methyl­ethanamine (4) (1.00 g, 5.71 mmol) was added under an argon atmosphere. The mixture was heated under argon at 368 K for 5 h. Toluene was evaporated under reduced pressure and the residue was suspended in hexane (30 ml). The resulting mixture was kept at 253 K for 10 h. The obtained precipitate was filtered off, washed with hexane (3 × 10 ml) and methanol (2 × 10ml), and dried under vacuum at room temperature to give 1.90 g (2.96 mmol, yield 79%) of 5 as a light-green powder, pure by TLC, m.p 455–458 K (decomp.). Green prisms were grown by slow crystallization from a hepta­ne–CH2Cl2 solvent mixture.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 3 ▸. C-bound H atoms were included in the refinement using the riding-model approximation with C—H distances of 0.93–0.97 Å, and with U iso(H) = 1.2 or 1.5U eq(C). The measurements of the 02, 002), 11, 02, 110, 12), 21, 200 and 35 reflections were affected by shielding by the beam stop and were therefore excluded from the refinement. A region of electron density, most probably disordered solvent mol­ecules, occupying voids of ca 1096 Å3 for an electron count of 419, was removed with the SQUEEZE procedure in PLATON (Spek, 2015 ▸) following unsuccessful attempts to model it as a plausible solvent mol­ecule. The stated formula mass, density, etc. do not include the disordered solvent.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
