In this paper, a new catalytic synthesis method for nitrogen-containing chemicals is introduced. Selenium as a catalyst and carbon monoxide as a carbonylation reagent can be used to synthesize asymmetric urea compounds, nitrogen-containing heterocyclic urea compounds and cyclic urea compounds through redox carbonylation Compounds and carbamates. In this new reaction system, the catalyst exhibits the phase transfer catalytic properties of the reaction process, the product is easily separated, and the catalyst can be recycled and reused.
