Preparation of Bis(trichloromethyl)Carbonate and Its Application to Synthesis of Direct Dyes

This paper introduced the study of the preparation of bis(trichloromethyl)carbonate(BTC) and its application to the synthesis of direct dyes.The study shows that the condition required by the preparation is mild and the yield afforded is excellent,and that the reactions with BTC in the synthesis of direct dyes are not only normally carried out under mild conditions and often afford good to excellent yields,but also cause fewer side reactions than ones with toxic phosgene or diphosgene do.With these advantages,BTC should be the ideal substitute for toxic phosgene and has a promising prospect with its application on the synthesis of direct dyes,high molecular materials,pharmaceutical intermediate,pesticides and other organic compounds.
