A Ni-catalyzed decarbonylative methylation of aromatic esters was achieved using methylaluminums as methylating agents. Dimethylaluminum chlorides uniquely worked as the methyl source. Because of the Lewis acidity of aluminum reagents, less reactive alkyl esters could also undergo the present methylation. By controlling the Lewis acidity of aluminum reagents, a chemoselective decarbonylative cross-coupling
使用甲基铝作为甲基化剂,可以实现镍催化的芳香族酯的脱羰甲基化。氯化二甲基铝独特地用作甲基源。由于铝试剂的路易斯酸度,反应性较低的烷基酯也可能会发生本甲基化。通过控制铝试剂的路易斯酸度,烷基酯和苯基酯之间的化学选择性脱羰交联是成功的。
