An efficient and selective transformation of 2,2,2-trifluoroethyl carbonyls into ureas/amides with amines is reported. This protocol allows the selective cleavage of the C–C bond of 2,2,2-trifluoroethyl carbonyls under transition metal-free and oxidant-free conditions, which is in contrast to the analogous C–F or C–CF3 bond functionalization. This reaction reveals the unexplored reactivity of 2,2,2-trifluoroethyl
据报道,2,2,2-三氟乙基羰基与胺有效且选择性地转化为脲/酰胺。该方案允许在无过渡金属和无氧化剂的条件下选择性裂解 2,2,2-三氟乙基羰基的 C-C 键,这与类似的 C-F 或 C-CF 3 键功能化相反。该反应揭示了 2,2,2-三氟乙基羰基的未开发反应性,并表现出广泛的底物范围和良好的官能团耐受性。
