摘要：

Symmetrical diarylureas can be prepared by purging an aromatic amine with carbon dioxide in the presence of a strong amidine base followed addition of solid commercially available Me(3)N.SO3. Work up is simply by dilution with water. The procedure is far simpler and safer than traditional methods using phosgene or isocyanates.
