Abstract: A Pd(OAc)2/[mmim]I ([mmim]I=1-methyl-3-methylimidazolium iodide) catalyst system was applied to the oxidative carbonylation of aliphatic amines, aromatic amines, and amino alcohols to carbamates, ureas, and 2-oxazolidinones under different conditions. The catalytic turnover frequencies (TOF, moles of amines converted per mole of catalyst per hour) were12417,17368, and4114h-1for the production of methyl N-phenyl carbamate, N,N′-diphenyl urea, and 2-benzoxazolinone, respectively.
