The insertion of arynes into P–O bonds for the preparation of o-hydroxy-substituted arylphosphine oxides, -phosphinates, and -phosphonates is described. This novel reaction leads to the simultaneous formation of C–P and C–O bonds in one step with good yields and regioselectivities under mild and transition-metal-free conditions. The easy follow-up transformations of the resulting o-hydroxyl group extend
描述了将芳烃插入到P–O键中以制备邻羟基取代的芳基膦氧化物,-次膦酸酯和-膦酸酯。这种新颖的反应可以一步一步同时形成C-P和C-O键,在温和且无过渡金属的条件下,具有良好的收率和区域选择性。所得邻羟基的容易的后续转化将这些反应扩展到其他邻位取代的芳基磷化合物的容易构造。
