Some Transformations of Mono-and Dichloro(diethoxyphosphoryl)acetaldehydes

摘要

Addition of ethanol and diethyl phosphonate to the carbonyl group of 2,2-dichloro-2-(diethoxyphosphoryl)-acetaldehyde has been studied, and the corresponding alpha-chloro ether, acetal, and phosphorylated metrifonate have been obtained. alpha,alpha-Dichloro-alpha-phosphoryl carbonyl compounds have been found to undergo haloform cleavage by the action of bases. Perkow reaction of mono- and dichloro(diethoxyphosphoryl)acetaldehydes with triethyl phosphite afforded diethyl 2-(diethoxyphosphoryl)ethenyl phosphates.
