N,N'-disubstituted ureas have been obtained in good yields by reaction of aromatic and aliphatic primary amines in alcohol solution with CO and O2 under mild conditions (70-90 deg C, 1 atm) and in the presence of catalytic amounts of PdCl2 or a palladium(II) complex.Under more drastic temperature and pressure conditions carbamate esters were obtained instead.In the aniline carbonylation, the catalysis involves the following reactions:
