Abstract

PURPOSE: To obtain the titled compound in high yields useful as a raw material for a tertiary phosphine through one step reaction requiring no catalyst, by reacting a tertiary phosphine sulfide prepared as by-products in organic synthetic reactions with phosgene.
CONSTITUTION: A tertiary phosphine sulfide shown by the formula I (R is 1W18C alkyl, 6W14C aryl, the three R may be the same or different) is reacted with phosgene to give a tertiary dichlorophosphine shown by the formula II. The reaction is carried out preferably in a solvent, e.g., acetonitrile, at -20W250°C. Tertiary phosphine sulfide prepared as a by-product in using tertiary phosphine as a desulfurizing agent can be used for a raw material. The obtained compound shown by the formula 2 can be converted easily into a tertiary phosphine or a tertiary phosphineimine.
