Selenium-Containing Heterocycles from Isoselenocyanates: Cycloaddition of Carbodiimides to Selenazetidines

The reactions of isoselenocyanates with carbodiimides in refluxing hexane afforded 1,3‐selenazetidine‐2,4‐diimines 3a–3h by a [2+2] cycloaddition in moderate‐to‐good yields. The molecular structure of 3a has been established by X‐ray crystallography.
