R = alkyl) presumably involves the direct participation of the triple bond, and, as with the allene derivatives, proceeds via a vinyl cation (99). This is supported by the fact that, despite the strong inductive effect of the triple bond, the rates of solvolysis of the acetylene derivatives (98), R = alkyl, are only slightly lowerWe are grateful to the Deutsche Forschungsgemeinschaft and to the Fonds der Chemischen Industrie for their support of our own work, which was carried out by,
The present paper describes the formation of silicon-carbon compounds (carbosilanes), the moIecular skeletons of which consist of alternate Si and C atoms, and which can be obtained by thermal decomposition of Si(CH3)4, CH3SiCI3, (CH3)2SiCIz, and (CH3)3SiCl. The description of the formation of carbosilanes is followed by a discussion of the reactions of polychlorinated carbosilanes with organometallic compounds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
