Abstract

We have successfully isolated the zinc carbamate complex (phen)Zn(OAc)(OC(=O)NHPh) (1, phen=1,10-phenanthroline), which is an intermediate in the Zn(OAc)2/phen-catalyzed synthesis of organic carbamates from CO2, amines, and Si(OMe)4. By analyzing the reaction mechanism based on the reactivity of 1 and DFT calculations, we improved the catalytic system and synthesized various organic carbamates—including polyurethane raw materials—by using CO2 at 1 atm.
