that takes advantage of diarylborinic acids as a cost-effective alternative to arylboronic acids for synthesis of diarylmethanes through metal-free reductive cross-coupling with N-tosylhydrazones of aromatic aldehydes and ketones. The procedure tolerates hydroxyl, halide, amine, and allyl functionality, complementary to the transition-metal catalyzed cross-coupling techniques.
本文介绍了一种实用有效的方法,该方法利用二芳基硼酸作为芳基硼酸的经济有效替代品,通过无金属的还原性与芳族醛和酮的N-甲苯磺酰hydr偶合来合成二芳基甲烷。该方法可耐受羟基,卤化物,胺和烯丙基官能团,与过渡金属催化的交叉偶联技术互补。
