Dialkyl heteroaroylphosphonates based on thiophene, pyrrole or furan have been prepared and their reactions with trimethyl phosphite investigated. Deoxygenation of the carbonyl groups in these heteroaroylphosphonates occurs to give carbene intermediates, which then undergo further reaction. In the case of

The reactions of unsaturated chloride polyether polyol with trimethyl phosphite have been studied by FTIR, which was prepared by copolymerization of ethanediol, allyl glycidyl ether and epoxychloropropane. The experimental results showed that the reaction included ester-exchange reaction, ester-exchange polymerization and
