Reversible Sn-Sn Triple Bond Dissociation in a Distannyne: Support for Charge-Shift Bonding Character.

Ting Yi Lai1, Lizhi Tao1, R David Britt1, Philip P Power1.   

Abstract

The tin-tin triple bond in the distannyne AriPr4SnSnAriPr4, AriPr4 = C6H3-2,6(C6H3-2,6-iPr2)2, undergoes reversible cleavage in deuterated toluene to afford two :SṅAriPr4 radicals in solution as shown by 1H nuclear magnetic resonance and electron paramagnetic resonance spectroscopy. Variable temperature data afforded an enthalpy of dissociation of ΔHdiss = 17.2 ± 1.7 kcal mol-1 via van't Hoff analysis.
