Abstract

Highly efficient synthesis of alkyl N-arylcarbamates from CO₂, anilines, and alcohols using the CeO₂ and 2-cyanopyridine catalyst system was substantiated by selecting branched alcohols, such as 2-propanol and cyclohexanol, with minimized formation of byproducts, such as dialkyl carbonates and picolinamide. The catalyst system is operable even at low CO₂ pressure (≤1 MPa), and the target carbamates were obtained with high arylamine-based yields (up to 94%).
