Corallo, Marcel published the artcileStudy of the reaction of α-chlorinated alkylphosphonyl dichlorides with alcohols and amines, Product Details of C5H10Cl3O3P, the publication is Phosphorus and Sulfur and the Related Elements (1978), 4(1), 19-25, database is CAplus.
Condensation reactions of alcs. and amines with Cl3CP(O)Cl2 and with α,α-dichlorinated alkylphosphonyl dichlorides were investigated. The best results were obtained in solution with Et3N as HCl trapping agent. Thus, reaction of Cl3CP(O)Cl2 with MeOH at -20° gave Cl3P(O)(OMe)Cl. Several side reactions occur, one leading to triethylammonium phosphonates. The exptl. conditions for the stepwise esterification of α-chlorinated phosphonyl dichlorides were also given.
Phosphorus and Sulfur and the Related Elements published new progress about 866-23-9. 866-23-9 belongs to chlorides-buliding-blocks, auxiliary class Aliphatic Chain, name is Diethyltrichloromethylphosphonate, and the molecular formula is C5H10Cl3O3P, Product Details of C5H10Cl3O3P.
