Immobilized Zn(Oac)(2) On Bipyridine-Based Periodic Mesoporous Organosilica For N-Formylation Of Amines With Co2 And Hydrosilanes

Zinc acetate (Zn(OAc)(2)) was successfully immobilized on a bipyridine-based periodic mesoporous organosilica (BPy-PMO-TMS), as confirmed by solid-state NMR and energy-dispersive X-ray spectroscopies, X-ray diffractometry, and nitrogen adsorption/desorption isotherm analyses. The immobilized Zn complex, Zn(OAc)(2)(BPy-PMO-TMS), exhibited good catalytic activity during the N-formylations of amines and amides with CO2 and PhSiH3 to produce the corresponding formamides. Zn(OAc)(2)(BPy-PMO-TMS) with a lower Zn loading was found to exhibit higher catalytic activity.
