An active catalytic system for the cross-dehydrogenative coupling (CDC) of a wide range secondary amines with silanes is reported. The iridium(III) derivatives [Ir(H)(X)(κ2-NSiDMQ)(L)] (NSiDMQ = {4,8-dimethylquinoline-2-yloxy}dimethylsilyl; L coe, X Cl, 2; OTf, 3; PCy3, 4; 5), which are stabilized by weak yet noticeable Ir···H–C agostic interaction between iridium and one C–H bonds 8-Me substituent NSiDMQ ligand, have been prepared fully characterized. These species proven to be effective catalysts CDC hydrosilanes. best performance (TOF1/2 79,300 h–1) was obtained using 5 (0.25 mol %), N-methylaniline, HSiMe2Ph. activity [Ir(H)(OTf)(κ2-NSiQ)(PCy3)] (10, NSiQ {quinoline-2-yloxy}dimethylsilyl) [Ir(H)(OTf)(κ2-NSiMQ)(PCy3)] (11, NSiMQ {4-methylquinoline-2-yloxy}dimethylsilyl), related but lacking substituent, markedly lower than that found 5. This fact highlights crucial role ligand in enhancing these complexes.
