The yields of the epoxides obtained from the reaction of 1,2-diols with the "triphenylphosphine-tetrachloromethane-potassium carbonate reagent" range from 27-85percent depending on the relative concentration of triphenylphosphine and diol.In the absence of heterogeneous potassium carbonate, reactions of 1,2-diols with triphenylphosphine-tetrachloromethane give largely 1,2-chlorohydrins.
