PROBLEM TO BE SOLVED: To obtain a 1,2-dioxyethane derivative in a high yield by using a phosphazenium compound as a catalyst on the reaction of an epoxy compound with a carboxylic acid ester, a carboxylic acid anhydride or a carbonate. SOLUTION: This method for producing a 1,2-dioxyethane compound comprises reacting an epoxy compound with an carboxylic acid ester, a carboxylic acid anhydride or a carbonate in the presence of a phosphazenium compound of the formula (R is a 1-10C hydrocarbon; Z- is a halogen anion, hydroxy anion, an alkoxy anion or the like), thus obtaining the corresponding 1,2-dioxyethane derivative, respectively. For example, phenyl glycidyl ether is dropped and reaction with phenyl acetate in the presence of tetrakis[tris(dimethylamino)phosphoranylidenamino]phosphonium of the formula to obtain 1,3-diphenoxy-2-propyl acetate in a production yield of 98%. The compound of the formula can exhibit an extremely high catalytic activity. |
