Фосфорилирование малонового эфира
Фосфорилирование малонового эфира
Господа, имеются ли у кого-либо из вас данные по фосфорилированию малонового эфира по метиленовому звену или может кто-то занимался подобным? Природа фосфорного заместителя не имеет принципиального значения.

Abstract
Alkali metal derivs. (I) of di-Et malonate, obtained by treating the ester with a liquid Na-K alloy, reacted with Ph2PCl to give Ph2PCH(CO2Et)2, which was not isolated but treated with S to give Ph2P(S)(CO2Et)2 (II), also formed in the reaction between I and Ph2PSCl. Alk. hydrolysis, followed by acid-catalyzed decarboxylation of II, gave the known Ph2P(S)CH2CO2H.
