Herein, we report the first example of molybdenum-catalyzed (E)-Selective anti-Markovnikov hydrosilylation alkynes. The reaction operates effectively with utilization minute amounts inexpensive, bench-stable pre-catalyst and ligand under mild conditions. Moreover, this process features advantages simple operation, excellent selectivity, broad functional groups tolerance.

Phosphine- or carbene-based soft ligands are customarily used in Rh and other late transition metal catalyzed alkene alkyne hydrosilylation hydrogenation. We report here an aziridine a 2-pyrrolidone with pyridyl sidearms, whose cationic Rh(I) complexes prove as excellent catalysts for hydrosilylating terminal olefins by Et3SiH giving anti-Markovnikov products selectively. To the best of our knowledge, [(2-pyrrolidone)-Rh]+ seems to be most active catalyst recording highest TOF 24000 h-1. It works remarkably (TOF: 714 h-1) even at 10 ppm concentration! Terminal alkynes hydrosilylated too give β-(Z)-vinylsilanes Both also hydrogenate alkenes doubly-hydrogenate alkynes, both internal, under ambient benchtop conditions. But hydrogenation, [(aziridine)-Rh]+ better. air-stable.
