The synthesis, characterization and X-ray crystal structures of two 2-naphthyl-substituted pyrazoles - 3-(2-naphthyl) pyrazole (1) and 5-(2-naphthyl)-3-trifluoromethyl-pyrazole (3) - are reported. In addition, the isolation and structural characterization of 5-hydroxy-3-(2-naphthyl)-5-trifluoromethyl-4,5-dihydropyrazole (2), an intermediate of the synthesis of 3, is included. Two simple methods of
报道了两种2-萘基取代的吡唑的合成,表征和X射线晶体结构-3-(2-萘基)吡唑(1)和5-(2-萘基)-3-三氟甲基-吡唑(3)- 。此外,隔离和5-羟基-3-(2-萘基)的结构表征-5-三氟甲基-4,5-二氢吡唑(2),中间的合成的3,是包括在内。还介绍了2的两种简单脱水方法。
