Abstract
3,3-Bis (chloromethyl) oxetane is prepared by a method which comprises reacting N,N-dimethyl formamide with thionyl chloride to produce Vilsmeier reagent, followed by the reaction of the Vilsmeier reagent with pentaerythritol to produce pentaerythritol monochlorohydrin. The pentaerythritol monochlorohydrin is then reacted with thionyl chloride to produce pentaerythritol trichlorohydrin, followed by the reaction of pentaerythritol trichlorohydrin with an alkali metal hydroxide or an alkaline earth metal hydroxide to 3,3-bis (chloromethyl) oxetane.
