摘要

A series of cyclometalated benzoquinoline complexes of Ir (III) catalyze the hydrogenation of the heterocyclic ring of quinolines under mild conditions. Our best catalyst is active in a significantly wider range of solvents than our previous systems. In the presence of a suitable base, the Ir (III) species is also able to hydrogenate the C O bonds of aldehydes. When quinolines and aldehydes are present together, the Ir (III) complex catalyzes a tandem ...
