Transition metal-catalyzed oxidative cleavage of carbon-carbon multiple bonds has emerged as a powerful tool in organic synthesis. High-valent oxometals, mostly of Ru, Os, Mn, Mo, W, and Re, were used catalytically as reactive oxygen transfer agents to the multiple bonds. Reported here for the first time are the organocatalytic versions of the oxidative cleavage reactions. Our method involves use of
过渡金属催化的碳-碳多键氧化裂解已成为有机合成中的有力工具。高价含氧金属,主要是 Ru、Os、Mn、Mo、W 和 Re,被用作催化多键的活性氧转移剂。这里首次报道了氧化裂解反应的有机催化版本。我们的方法涉及使用碘代三甲苯作为有效的有机催化剂,在无金属条件下生成活性芳基(羟基)-λ(3)-碘烷 5 和间氯过苯甲酸(m-CPBA)作为末端氧化剂。环状和无环烯烃以及脂肪族和芳香族炔烃在有机催化条件下顺利裂解为羧酸。
