New polymer-supported phosphonate reagents have been prepared and evaluated for the synthesis of Za,b-unsaturated esters.
It has been shown that over-all conversions of carbonyl compounds to olefins, similar to the well known "Wittig" reaction, could be effected using silicon-substituted carbanions 1 . Recently, an alkyl lithiomethylacetate was reported to be an excellent reagent for the synthesis of a,%-unsaturated ca

Recently, we have reported that a new type Grignard reagent derived from ethyl a-phenylsulfinylacetate and alkylmagnesium halides has a good reactivity at the a-carbon atom toward aldehydes and ketones to give the corresponding
