at mercury cathode, behaves as a mild effective base to deprotonate the acidic hydrogen from tosylhydrazones of benzophenone (1), benzaldehyde (2), cyclohexanone (3), benzoin (4), acetophenone (5), and benzil (6) finally affording tetraphenylethene (1a), trans-stilbene (2a), cyclohexene (3a), deoxybenzoin (4a), acetophenone azine (5a), and 4,5-diphenyl-1-tosylamino-1,2,3-triazole (6a) respectively in
通过电化学还原二甲基甲酰胺 (DMF) 中的分子氧在汞阴极上原位生成的超氧离子 (O2\ewdot) 作为一种温和有效的碱来使二苯甲酮 (1)、苯甲醛 (2)、环己酮的甲苯磺酰腙中的酸性氢去质子化(3)、安息香(4)、苯乙酮(5)和苯偶氮(6)最终得到四苯乙炔(1a)、反式二苯乙烯(2a)、环己烯(3a)、脱氧安息香(4a)、苯乙酮吖嗪(5a)和4,5-diphenyl-1-tosylamino-1,2,3-triazole (6a) 分别以良好到极好的收率。
