    With cheap and easily available nonmetal selenium as catalyst,carbon monoxide as carbonylation reagent,oxygen as oxi-dant,the target product 1,3-diazepan-2-one can be obtained in yield of 71%via one-pot selenium-catalyzed intramolecular oxidative carbonylation of 1,4-butanediamine at the optimal conditions. This method has the merits of short synthetic route,high atom econo-my,low cost and environmentally benign approach.
