Specifications: Forty unsymmetric N-phenyl-N-pyridyl urea derivatives were synthesized in moderate-to-good yields by one-pot reductive carbonylation of nitroaromatics using selenium or selenium dioxide as the catalyst, aminopyrimidine derivatives as co-reagents, and carbon monoxide as the carbonyl source. The reaction parameters were investigated, as was the reusability of the catalysts. We found that selenium- or selenium dioxide.
