Chlorination and cyclodehydration of 1,2-diols with the “triphenylphosphate-tetrachloromethane-potassium carbonate” reagent

Abstract The yields of the epoxides obtained from the reaction of 1,2-diols with the “triphenyl-phosphine-tetrachloromethane-potassium carbonate reagent” range from 27–85% depending on the relative concentration of triphenylphosphine and diol. In the absence of heterogeneous potassium carbonate, reactions of 1,2-diols with triphenylphosphine-tetra-chloromethane give largely 1,2-chlorohydrins.
