醇和酯在四叔丁基锌酸二锂(1 mol%)催化下,0℃反应1.5 h可得相应的酯交换产物,14例收率38%~>99%。加入4?型分子筛吸收生成的醇可提高收率,且当反应体系中存在水、正丙胺或三乙胺时仍可正常反应,而当反应物为叔丁醇、苯酚 Alcohols and esters were reacted at 0 ℃ for 1.5 h under the catalysis of dilithium tetra (tert-butyl) zincate (1 mol%) to obtain the corresponding transesterification products. The yields of the esters and esters were 14% to 99%. Addition of 4? Molecular sieve to the alcohol produced can enhance the yield, and can still react normally when water, n-propylamine or triethylamine is present in the reaction system. When the reactant is t-butanol, phenol
