An extraordinarily efficient hybrid acids‐assisted, palladium‐catalyzed and chelating‐group‐assisted CH bond activation of N‐sulfonyl‐2‐aminobiaryls and their annulations with [60]fullerene via sequential CC and CN bond formation at room temperature to afford [60]fulleroazepines is demonstrated. The formation of [60]fulleroazepines is highly regioselective and tolerant to both electron‐withdrawing
一个非常高效的混合酸辅助,钯-催化的和螯合基团的辅助Ç 的H键活化Ñ磺酰基-2- aminobiaryls及其与[60]富勒烯annulations经由连续的C语言 C和C N键形成在室温下可得到[60]富勒氮杂。[60]富勒氮杂的形成具有高度的区域选择性,并且对芳基部分的吸电子基团和给电子基团都具有耐受性,并且该反应以良好的收率得到单官能化的富勒烯(分离出的C高达54%,基于转化的C 60高达92%)。
