Abstract
Hydride reduction of the bound nitrosyl ligand in [Ru(ttp)(NO)(1-MeIm)]BF(4) (upsilon NO 1862 cm(-1); ttp=tetratolylporphyrinato dianion) by sodium borohydride in anhydrous methanol leads to the generation of the first experimentally observable heme-model-HNO complex [Ru(ttp)(HNO)(1-MeIm)] in 77% isolated yield. The (1)H NMR spectrum of the compound in CDCl(3) shows a downfield resonance at 13.64 ppm assigned to the proton of the HNO ligand, and this peak splits into a doublet (JNH Hz) in the [Ru(ttp)(H(15)NO)(1-MeIm)] derivative. The IR spectrum of the solid as a KBr pellet reveals a strong band at 1380 cm(-1) assigned to upsilon NO; this band shifts to 1348 cm(-1) in the isotope-labeled [Ru(ttp)(H(15)NO)(1-MeIm)].Entities:
