Carbenes organosilicon complexes

Another organosilicon carbene complex is formed by treating chro-... 

Important progress has been made in the study of the process since the discovery and development of well-defined ruthenium carbene complexes. The interest in the reaction as a synthetic tool for organic synthesis has been growing, among others, because of its atom economy. For recent reviews on enyne metathesis see Refs. [91-93]. For a review on the application of enyne metathesis in organosilicon chemistry see Ref. [6]. 

In contrast to other alkenyl-substituted organosilicon compounds, a metathetical conversion of divinylsilyl derivatives in the ADMET polymerization as well as the RCM process does not occur in the presence of well-defined W, Mo, and Ru carbene complexes because of stereoelectronic effects of the silyl group stimulating non-productive cleavage of the disilyhnetallacyclobutane intermediate [16],...
