The radical coupling of isocyanides and alcohols/phenols promoted by silver in the presence of water is reported for the first time, which led to the formation of diverse carbamates. In contrast to the well-known 1,1-addition to form imidoyl radicals, a novel reaction mechanism, involving sequential hydration of isocyanides and coupling with alkoxyl/phenoxyl radicals, is disclosed by combining experimental
首次报道了银在水存在下促进的异氰酸酯和醇/酚的自由基偶联,这导致形成各种氨基甲酸酯。与形成酰亚胺基的众所周知的1,1-加成相反,通过结合实验和理论研究,揭示了一种新颖的反应机理,其中涉及异氰酸酯的顺序水合和与烷氧基/苯氧基的偶合。
