borrowing-hydrogen methodology, this contribution describes the switch of the selectivity towards N-alkylation. Starting from indolines, N-alkylation was efficiently done using a tricarbonyl(cyclopentadienone) iron complex as the catalyst in 2,2,2-trifluoroethanol. Notably, performing the one pot N-alkylation of indolines, followed by oxidation using a FeBr3/TEMPO catalyst with t-BuOOH, the corresponding N-alkylated
与通过借氢方法进行的经典铁催化吲哚 C3 烷基化相比,该贡献描述了选择性向 N-烷基化的转变。以二氢吲哚为原料,使用三羰基(环戊二烯酮)铁络合物作为催化剂,在 2,2,2-三氟乙醇中有效地进行 N-烷基化。值得注意的是,对二氢吲哚进行一锅N-烷基化,然后使用FeBr 3 /TEMPO催化剂与t- BuOOH进行氧化,得到相应的N-烷基化吲哚。
