The meta-carboxylation of arenes containing pyridine and other azine-directing groups is reported. Using carbon tetrabromide as the C1 source, ruthenium(III) trichloride catalysis enables functionalization of the arene meta-C–H position, affording carboxy methyl ester products after in situ reaction with methanol.
报道了含有吡啶和其他嗪指导基团的芳烃的间羧化。使用四溴化碳作为C1来源,三氯化钌(III)催化能够使芳烃间位-C–H位官能化,在与甲醇原位反应后得到羧甲基酯产物。
