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

Density functional theory calculations of the title reaction, P(OCH₃)₃ + (H₂O)(n) in CH₃CN, were conducted, where n is the number of water molecules. Two routes, the routes suggested by (A) Aksnes and (B) Arbuzov, were traced with various n values.

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

Trimethyl phosphite, (MeO)(3)P, is introduced as an efficient and selective trap in oxiranylcarbinyl radical (2) systems, formed from haloepoxides 8-13 under thermal AIBN/n-Bu(3)SnH conditions at about 80 degrees C. Initially, the transformations of 8-13, in the absence of phosphite, to
