ABSTRACT:
Bicyclo[4.3.0]1,4,7-triazanony-6-ene-5-one may be made easily, in good yield and in one step by reacting diethyl oxalate with a diethylene triamine. The bicyclo[4.3.0]1,4,7-triazanon-6-ene-5-one material made by this process may be used to selectively separate metal ions from solution, or complexed together with a metal ion act as a catalyst. Surprisingly, related bicyclic triazines do not show the ability to complex with metal ions and precipitate them from solution.
