In this study, we developed a catalytic system for the C-alkylation of a methyl group on N-heteroaromatic compounds, including pyridine, pyrimidine, pyrazine, quinoline, quinoxaline, and isoquinoline, using alcohols based on a hydrogen-borrowing process with [Cp*IrCl2]2 (Cp*: η5-pentamethylcyclopentadienyl) combined with potassium t-butoxide and 18-crown-6-ether as the catalyst precursor.
在这项研究中,我们开发了一种催化体系,用于使用N [Cp * IrCl 2 ] 2(Cp *:η5-五甲基环戊二烯基)与叔丁醇钾和18-冠-6-醚组合作为催化剂前体。
