Conclusions
-
1.
Ethyldichlorophosphine adds to the monoesters of maleic acid in the 1,4-position. The reaction with maleic acid leads to the formation, depending on the reaction conditions, of either maleic anhydride or chlorosuccinic anhydride.
-
2.
The reaction of ethyldichlorophosphine with pyromucic leads to the formation of the acid chloride of pyromucic acid.
