Electroreduction of diethyl(trichloromethyl)phosphonate in the presence of aldehydes or ketones replaces the O atom of the carbonyl group by a dichloromethylene group. The yield of 1,1-dichloroethene product decreases substantially if the carbonyl compound carries strongly acidic hydrogen. In several cases the conversion of the 4-membered ring Wittig intermediate into its corresponding carbanion by heterolytic P-C bond cleavage was observed The intermediate carbanion is sufficiently stable to be intercepted by proton abstraction. These observations suggest that the decomposition of the Wittig 4-membered ring intermediate occurs along a 2-step pathway.
