由全氟酰氟和氟砜基二氟乙酰氟分别合成了全氟烷基羧酸全氟苯酯(1)和全氟苯氧羰基二氟甲烷磷酸全氟苯酯(2)。研究了1和2的亲核取代反应,发现1比全氟磺酸全氟苯酯更易与亲核试剂作用,试剂均进攻于羧基碳上。在2的亲核反应中,其羧基碳亦比磺基硫原子更易受试剂的进攻。 Perfluoroalkylcarboxylic acid perfluorophenyl ester (1) and perfluorophenoxycarbonyldifluorophenyl phosphate perfluorophenyl ester (2) were synthesized from perfluoroacyl fluoride and fluorosulfonyl difluoroacetyl fluoride respectively. The nucleophilic substitution reactions of 1 and 2 were studied and found that 1 was more likely to act as a nucleophile than perfluorophenyl perfluorosulfonate, with the reagents attacking on the carboxyl carbon. In the 2 nucleophilic reaction, the carboxyl carbon is also more vulnerable than the sulfo sulfur atom attack by reagents.
