The reaction of ?- and ?- oxides with chlorides of phosphorus

Abstract

1. When α-methyltrimethylene oxide, tetrahydrofuran, and tetrahydrosilvan react with phosphorus trichloride, chloroalkyl esters of phosphorous acid are formed in 50–55% yields. 2. The reaction of tetrahydrofuran with PCl5 apparently proceeds by a type of exchange reaction with opening of the ring at both C-O bonds and formation of 1,4-dichlorobutane and phosphorus oxychloride.
