Reaction Steps

USSR Patent Specification No. 173,763 also describes the preparation of beta-chloroformyl-ethyl ethyl phosphinic acid chloride by reacting ethyldichlorophosphine and acrylic acid in benzene at temperatures of up to 60° C., over a period of 2.5 hours, and distilling the reaction product, which is obtained in a yield of 62.4 % of the theoretical. In the absence of the benzene solvent, the temperature increases spontaneously to 150° C., and the yield falls to 31.6 % of the theoretical. The reaction of ethyldichlorophosphine with methacrylic acid, in the absence of a solvent, produces beta-chloroformyl-beta-methyl-ethyl ethyl phosphinic acid chloride in a yield of 37.2 % of the theoretical.
