Palladium(0)-catalyzed Suzuki cross-coupling reactions of the bis(triflates) of 2′,4-dihydroxybenzophenones afforded 2′,4-diarylbenzophenones. The reactions proceeded with very good site selectivity in favour of the 4-position.
钯(0)催化的 2',4-二羟基二苯甲酮的双(三氟甲磺酸酯)的 Suzuki 交叉偶联反应得到 2',4-二芳基二苯甲酮。反应以非常好的位点选择性进行,有利于 4 位。
