Abstract
1. The reaction of the diethyl ester of carbethoxymethylphosphinic acid with aldehydes proceeds stereospecifically and leads to unsaturated esters with a trans-configuration of the double bond that arises. 2. The reaction of carbethoxymethylenetriphenylphosphorane and the diethyl ester of carbethoxymethylphosphinic acid with sterically unhindered ketones leads to a mixture of cis-trans isomers. 3. The results obtained agree with the generally accepted scheme of the Wittig reaction.
