When electron-rich benzopinacols are electrooxidized or treated with catalytic amounts of NOBF4 the corresponding pinacolones are obtained in quantitative yields. Control experiments rule out the possibility of adventitious acid intervening in the reaction and a radical-cation chain electron-transfer mechanism is proposed.
当富电子的苯并
频哪醇被电氧化或用催化量的NOBF 4处理时,可以定量产率获得相应的
频哪醇。控制实验排除了不定酸介入反应的可能性,并提出了自由基-阳离子链电子转移机理。
