3-tetrafluoroethyl-, 2,2,3,3,4,4,5,5-octafluorobutyl- and 2,2,3,3,4,4,5,5,6,6,7,7-dodecafluorohexyl-carbinols were investigated in the presence of various catalysts. It was found that the conversion of starting dialkyl carbonate increases upon increasing the length of fluorine-containing radical in the presence of sodium alkoxide. It was shown that the maximum conversion of dimethyl carbonate (90%) was achieved in

氟基团长度的增加,起始
碳酸二烷基酯的转化率增加。结果表明,在使用催化剂(如 K 2 CO 3 )与 2,2,3,
3,4,4,5,5-octafluoropentan-1-ol 的反应中,
碳酸二甲酯的转化率最高(90%)、NaOH 和醇
