electron-deficient (trifluoromethylsulfonyl)benzene derivatives, as a phenyl precursor, was critical to realizing the present transformation. Moreover, the DFT calculations indicated that the present transformation proceeds via a concerted homolytic aromatic substitution rather than via a stepwise one involving the formation of a cyclohexadienyl radical intermediate.
使用光激发的 4-苯甲酰吡啶作为氢原子转移,在连接到醚和 N-Boc-胺的杂原子上的非酸性 C(sp 3 )–H 键上实现了一步苯基化( HAT)催化剂。作为苯基前体的缺电子(三氟甲基磺酰基)苯衍生物的设计对于实现目前的转变至关重要。此外,DFT计算表明,本发明的转化是通过协同均裂芳族取代进行的,而不是通过涉及环己二烯基自由基中间体形成的逐步取代进行的。
