Without using phosgene, a series of new unsymmetric N,N′ -dipyridylurea derivatives have been synthesized in moderate to good yields by the one-pot reductive carbonylation of substituted nitropyridines. These reactions utilize selenium or selenium dioxide as the catalyst, aminopyridine derivatives as co-reagents, and carbon monoxide as the carbonyl source.
