✦ Synopsis

I-Phenylthio-l-trimethylsilylalkanes(1) are prepared in high yie'd from l,l-bis(phenylthio)acetals(2) by reaction vith lithium nanhthalenide(3) followed by chlorotrimethylsilane. cx-Silylcarbanion § are formed from the alkanes(1) and lithium naphthalenide(3). Subsequent reaction vith cerbonyl compounds gave the olefins(4) via the Peterson reaction.

A novel method is reported for the transformation of vicinal diols to olefins. This methodology consists in the conversion of iodothiocarbonates such as 16 to olefin 17 with phenyl lithium in excellent yield. Compounds 7 and 12 were prepared by this methodology in order to determine if they would be
