Title tandem reaction was achieved by using α-(trimethylsilyl)-alkylphosphine chalcogenides and the lithio derivative of 2-hydroxytetrahydropyran. The Horner-Emmons reaction of the tandem products was accomplished to give the corresponding 2-(β-styryl)tet

The synthesis of a variety of phosphoryl-substituted sulfines 5 by the reaction of α-silyl carbanions with sulfur dioxide is described.For characterization purposes the prepared sulfines were converted into their cycloadducts 6 with 2,3-dimethyl-1,3-butad
The Reactions of Tris(trimethylsilyl)methyl-lithium with Some Carbon Electrophiles

Tris(trimethylsilyl)methyl-lithium (1) reacts with non-enolisable aldehydes, ketones, and acid chlorides, and with some epoxides, with the formation of carbon-carbon bonds.This method of preparing functionalized silanes is limited by the readiness with which (1) abstracts a proton, if one is available, rather than attack at carbon.In the reaction with epoxides, the product alkoxide can transfer a silyl group from carbon to oxygen, and in one case the intermediate so formed reacts to give a cyclopropane (32) in what is a homologue of the Peterson reaction.The 1,4-transfer of a silyl group occurs in other systems when the resulting carbanion is stabilised by such groups as phenylthio and diphenylphosphinoyl.
