Sulfones ethylene derivatives

A major detraction to the p-silyl sulfone route to alkenes is its narrow scope, owing to the paucity of methods for preparing the requisite p-silyl sulfones. The method has so far been largely restricted to monosubstituted and 1,1-disubstituted ethylene derivatives because the P-silyl sulfones have usually been most conveniently and economically prepared by the alkylation of a sulfone anion with iodomethyl-trimethylsilane. Unfortunately higher haloalkylsilanes are difficult to prepare and their alkylation chemistry remains unexplored. [Pg.1002]
