摘要

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.
