system with coupled catalytic cycles is described that allows radical reduction by catalyzed hydrogen atom transfer (CHAT) from transition metal hydrides. These intermediates are generated through H2 activation. Radical generation is carried out by titanocene catalyzed electron transfer to epoxides. The reaction provides a novel entry into the atom-economical reduction of radicals that has long been
描述了具有耦合的催化循环的系统,其允许通过从过渡金属氢化物催化的氢原子转移(CHAT)进行自由基还原。这些中间体是通过H 2活化而产生的。自由基的产生是通过钛茂催化的电子转移到环氧化物上进行的。该反应为自由基的原子经济还原提供了新的途径,长期以来一直将其视为自由基化学工业应用的关键问题。
