Oxidative carbonylation of amines with alcohols provides an environmentally benign pathway to isocyanates and carbamates. Currently, the most active catalysts for the oxidative carbonylation of aniline with methanol are Pd-based catalysts. To further improve the economic feasibility of the carbamate synthesis process, we have investigated the activity of CuCl2-NaI, CuCl2-NaCl, and CuCl-NaI at 438 K and 0.41 MPa by in situ infrared spectroscopy. The activity of the catalysts for carbamate synthesis increased in the order: CuCl2-NaCl
