Methyl 1-alkoxy-3-perfluoroalkyl-2-naphthoates 5 were synthesized by heating appropriately substituted 2-triphenylphosphoranylidene-2-butenoates 3 in xylenes at 250°C in a sealed tube. Compounds 3 were obtained via an intramolecular Wittig reaction of 2-alkoxycarbonylbenzyltriphenylphosphonium bromide (1) with methyl 2-perfluoroalkynoates 2 in the presence of potassium carbonate.
1- 烷氧基-3-全氟烷基-2-萘甲酸甲酯 5 是在密封管中于 250°C 下在二甲苯中加热适当取代的 2-三苯基膦亚基-2-丁烯酸甲酯 3 而合成的。化合物 3 是通过 2-烷氧基羰基苄基三苯基溴化膦 (1) 与 2-全氟炔酸甲酯 2 在碳酸钾存在下发生分子内 Wittig 反应而得到的。
