采用Pd(OAc)2/[mmim]I催化体系,在不同反应条件下可以将烷基胺、芳香胺及氨基醇(酚)一步转化为氨基甲酸酯、脲和2-噁唑啉酮.N-苯基氨基甲酸甲酯、二苯基脲及苯并-2-噁唑酮的催化转化频率分别为12417,17638和4114h^-1.
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) were 12 417, 17 368, and 4 114 h^-1 for the production of methyl N-phenyl carbamate, N, N'-diphenyl urea, and 2-benzoxazolinone, respectively.
