Abstract

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.
