【摘要】 以3-三氟甲基-4-氨基-5-巯基-1,2,4-三唑(1)为原料,与芳醛在冰醋酸中缩合得相应Schiff碱(2～5),(2～5)与各种仲胺和劳胺在室温下反应,制得24个新的Mannich碱(6～9),利用IR,~1H NMR、MS和元素分析确定了这些化合物的结构。更多还原

【Abstract】 The reaction of 3 - trifluoromethyl - 4 - amino - 5 - mercapto - 1,2,4- triazole (1) with aromatic aldehydes gave the Schiff bases(2 - 5) . The Mannich reaction, of 2 - 5 led to twenty four new 1,2,4 - triazole Mannich bases(6 - 9) . The structures of these Mannich bases were confirmed by elemental analysis, IR,1H NMR and MS spectra.更多还原
