The first base-metal catalysed coupling of primary alcohols with methyl-N-heteroaromatics is reported. The use of an earth abundant and nonprecious NiBr2/L1 system enables access to a series of C(sp3)-alkylated N-heteroaromatics. Mechanistic studies have established the participation of a hydrogen-borrowing strategy for α-alkylation.

金属NiBr 2 / L1系统可以访问一系列C(sp 3)-烷基化的N-杂芳族化合物。机理研究已经确立了氢借用策略用于α-烷基化的参与。
