Catalyzed by Ir[dF(CF3)ppy]2(dtbbpy)PF6, the coupling of potassium organotrifluoroborates with Baylis–Hillman derivatives under visible light irradiation has been developed. Based on the mechanism of reductive quenching cycle, it provides an easy, mild, efficient method for the synthesis of a variety of α,β-unsaturated carboxylic esters derivatives in a broad scope of the substrates.
在Ir [dF(CF 3)ppy] 2(dtbbpy)PF 6的催化下,开发了有机三氟硼酸钾与Baylis-Hillman衍生物在可见光下的偶联。基于还原淬灭循环的机理,它提供了一种简便,温和,有效的方法,可在广泛的底物中合成多种α,β-不饱和羧酸酯衍生物。
