Group IB and IIB Metals

Kinetic studies on catalytic amine carbonylation reactions are scarce, although Brackman (13) has reported kinetics on a copper(I)-copper(II) catalyzed production of ureas from cyclic secondary amines using carbon monoxide-oxygen mixtures at ambient conditions. Saegusa and coworkers (14) used cuprous salts and other group IB and IIB metal compounds to car bony late piperidine to N-formylpiperidine under more severe conditions. We have published (15) a brief report involving some of the studies described in this paper.
