以Cs_2CO_3(1.2倍摩尔量)为碱,t-BuOOt-Bu或t-BuON=NOt-Bu(0.2倍摩尔量)为自由基源,在2-丙醇(80倍摩尔量)中于120℃或50℃下反应3或24 h,卤代(包括氯、溴、碘)芳烃被还原成芳烃。20例收率81%~100%。氯苯得苯的收率仅为8%。
Using t-BuOOt-Bu or t-BuON = NOt-Bu (0.2-fold molar amount) as free radical source in Cs 2 CO 3 (1.2 times molar amount) Or 50 ℃ for 3 or 24 h, halogenated (including chlorine, bromine and iodine) aromatics are reduced to aromatics. 20 cases of 81% to 100% yield. The yield of chlorobenzene was only 8%.
