Abstract:

A facile, efficient and cost-effective approach to 1,3-dibenzylurea was reported. With cheap and recyclable nonmetal selenium as catalyst, carbon monoxide instead of phosgene derivatives as carbonylation agent and oxygen as oxidant, the selenium-catalyzed oxidative carbonylation reaction of benzylamines can proceed efficiently in one-pot manner in the presence of triethylamine to afford the desired 1,3-dibenzylureas mostly in moderate to excellent yields. Selenium catalyst can be easily recovered due to its phase-transfer catalytic function and recycled.
