An unusual oxidative palladium-catalyzed rearrangement of diaryl alkenyl carbinols to β,β-diaryl α,β-unsaturated ketones is described. The geometry of the alkene product is not determined by the electronic nature of the aryl substitutents but rather is determined by substitution pattern on the aryl rings. The reaction proceeds in good yields, utilizes oxygen at atmospheric pressure as the terminal
描述了不寻常的氧化钯催化的二芳基烯基甲醇向β,β-二芳基α,β-不饱和酮的重排。烯烃产物的几何形状不是由芳基取代基的电子性质决定的,而是由芳基环上的取代图案决定的。该反应以良好的收率进行,利用大气压下的氧气作为末端氧化剂,并容许芳基环上的各种官能团。
