• 1-Dimethylamino-1-methoxy-1-alkenes (ketene <I>O</I>,<I>N</I>-acetals), 1-dimethylamino-1-ethylthio-1-alkenes (ketene <I>S</I>,<I>N</I>-acetals) and 1,1-bis(dimethylamino)ethylene (ketene <I>N</I>,<I>N</I>-acetal) reacted with diethyl phosphite to give the corresponding (<I>E</I>)-diethyl 1-dimethylamino-1-alkenylphosphonates. Although ketene diethylacetal (ketene <I>O</I>,<I>O</I>-acetal) reacted with diethyl phosphite to give diethyl 1,1-diethoxy-1-ethylphosphonate, 1,1-bis(ethylthio)-1-alkenes (ketene <I>S</I>,<I>S</I>-acetals) did not react with diethyl phosphite.
