| Abstract: | Presented herein is a set of bimetallic and trimetallic “coordination booster‐catalyst” assemblies in which the coordination complexes RuII(terpy)2] and OsII(terpy)2] acted as boosters for enhancement of the catalytic activity of RuII(NHC)(para‐cymene)]‐based catalytic site. The boosters accelerated the oxidative loss of para‐cymene from the catalytic site to generate the active catalyst during the oxidation of alkenes and alkynes into corresponding aldehydes, ketones and diketones. It was found that the boosting efficiency of the OsII(terpy)2] units was considerably higher than its congener RuII(terpy)2] unit in these assemblies. Mechanistic studies were conducted to understand this unique improvement. |
