Facile synthesis of urea derivatives under mild conditions†
†
Dedicated to Prof. Antonino Fava on the occasion of his seventieth birthday.
Abstract
Urea derivatives were readily synthesized in good yields under quite mild conditions, i.e., at ambient pressure and room temperature by sulfur-assisted carbonylation of primary amines with carbon monoxide followed by oxidation of the resulting ammonium thiocarbamates with molecular oxygen.
