defunctionalization of sp3 C–heteroatom and sp3 C–C bonds with triplet ketone catalysts and bipyridine additives is disclosed. This protocol is characterized by its broad scope without recourse to transition metal catalysts or stoichiometric exogeneous reductants, thus offering a complementary technique for activating σ sp3 C–C(heteroatom) bonds. Preliminary mechanistic studies suggest that the presence
公开了一种使用三线态酮催化剂和联吡啶添加剂实现 sp 3 C-杂原子和 sp 3 C-C 键的光诱导去功能化的一般策略。该协议的特点是其范围广泛,无需使用过渡金属催化剂或化学计量外源还原剂,从而为激活 σ sp 3 C-C(杂原子)键提供了一种补充技术。初步机理研究表明,2,2'-联吡啶的存在提高了酮基自由基中间体的寿命。
