The CO2-involved synthesis of chemicals is of significance. In this work, we found that 1-alkyl-3-methylimidazolium ionic liquids (ILs) had high efficiency for catalyzing the formylation of amines using CO2 and phenylsilane at room temperature, producing the corresponding formylated products in excellent yields under the metal-free condition. The ILs acted as bifunctional catalysts, which activated the Si-H bond of phenylsilane to react with CO2 to form the formoxysilane intermediate and simultaneously activated the amine substrate through the hydrogen bond. Moreover, the imidazolium cation and the anions of the ILs showed an excellent synergistic effect on catalyzing the formylation of amines.

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.

Pd-catalyzed highly para-selective arylations of monosubstituted simple arenes with arylboronic acids to widely existed biaryls have been developed. Inspired by requisite amide-directing groups in reported selective oxidative couplings, amide ligands, especially DMF, are designed and found to be critical for the selectivity control in current arylations.
