We describe a general and efficient transition-metal free C–C bond cross-coupling of (hetero)aryl ethers and diarylmethanes via C(sp2)–O bond cleavage. The coupling reactions mediated by KHMDS proceeded well with high efficiency, broad substrate scope, and good functional group tolerance. The robustness and practicability of this protocol also have been demonstrated by easy gram-scale preparation and
我们描述了(杂)芳基醚和二芳基甲烷通过 C(sp 2 )-O 键断裂的通用且有效的无过渡金属 C-C 键交叉偶联。KHMDS介导的偶联反应效率高、底物范围广、官能团耐受性好。该协议的稳健性和实用性也已通过简单的克级制备和多样化的产品衍生化得到证明。
