The formation of aldehydes from the photochemically activated reaction of Cp*Ir(CO)(Cl)(CH2R) complexes with water
摘要:
The iridium complexes Cp*Ir(CO)(Cl)(CH2R), which do not contain any beta-hydrogen atoms, react with water to form aldehydes. This reaction was found to be photochemically activated, and a possible pathway involving radical intermediates has been proposed and studied experimentally and computationally.

The synthesis of N-unprotected 2-aryl-3-cyanoindoles was realized via the Mn(III)-mediated radical cascade cyclization of o-alkenyl aromatic isocyanides with boronic acids. A possible mechanism involving a sequential intermolecular radical addition, intramolecular cyclization, and cleavage of the C–C bond under mild reaction conditions is proposed. Mechanism studies show that H2O or O2 might provide
N-未保护的 2-芳基-3-氰基吲哚的合成是通过 Mn(III) 介导的邻烯基芳族异氰化物与硼酸的自由基级联环化来实现的。提出了一种可能的机制,包括在温和的反应条件下连续分子间自由基加成、分子内环化和 C-C 键断裂。机理研究表明,H 2 O 或O 2可能为消除苯甲醛提供氧源。
