complexes ligated by strongly σ-donating cyclic (amino)(alkyl)carbenes (CAACs) show unique catalytic activity for the selective hydrogenation of aromatic ketones and phenols by reducing the aryl groups. The use of CAAC ligands is essential for achieving high selectivity and conversion. This method is characterized by its good compatibility with unsaturated ketones, esters, carboxylic acids, amides, and

Dioxygen activation with both cyclic (amino)(alkyl)carbenes and di(amino)carbenes at ambient temperature is described. Theoretical studies suggest that electron rearrangement from the doubly filled σ orbital of carbene carbon to its vacant p orbital through the π* antibonding orbital of 3O2 can be considered for Ccarbene–O bond formation.
描述了在环境温度下用环状(氨基)(烷基)卡宾和二(氨基)卡宾进行的双氧活化。理论研究表明,对于碳卡宾-O键的形成,可以考虑将电子从卡宾碳的双填充σ轨道通过3 O 2的π*反键轨道重排至其空位p轨道。
