Oxidative alkoxycarbonylation of aniline using homogeneous catalysts

Article abstract of DOI:10.1016/0304-5102(91)80038-5

In this communication, preliminary data on the homogeneously catalyzed oxidative alkoxycarbonylation of aniline to N,N-diphenyl urea and N-phenyl carbamate has been reported. The aim of this work was to evaluate performance of a variety of Pd, Ru and Rh complex catalysts for the above reaction. The activity and selectivity of the catalyst are highest with iodine-containing ligands and depend on the ease with which the catalyst precusor can be converted into an active catalytic intermediate.
