3 CLi, reacts with allyl, phenyl, benzyl, n-propyl and n-butyl glycidyl ethers in THF at -5 °C to give 1-oxa-2-silacyclopentane derivatives. It seems that ring closure is facilitated by conversion of the Si-H bond into an Si-O bond. Glycidyl methacrylate (GM) random copolymers with 4-methyl-and 4-methoxy styrene, synthesized by solution free radical polymerization at 70 (±1) °C with α,α-azobis(isobutyronitrile) (AIBN) as initiator, contained pendant epoxide functions. Treatment of these with (HSiMe 2 ) 3 CLi did not lead to intramolecular nucleophilic attack as found for simple epoxides.
Organo-silicon compounds S 0060New Straightforward Route for the Synthesis of Some 1-Oxa-2-silacyclopentane Derivatives. -Title compounds (III) are obtained by the reaction of glycidyl ethers (I) with a silylmethyllithium reagent (II) bearing hydride groups on silicon. The reaction mechanism, which is quite different from that observed with trimethylsilyl analogues, is discussed. -(SAFA*, K. D.; SHAHRIVAR, M.; TOFANGDARZADEH, S.; HASSANPOUR, A.; J. Heterocycl.

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.
