Synthesis, crystal structure, and thermolysis of the first tetracoordinate 1lambda4,2-selenazetidines: aziridine formation reaction from a four-membered heterocycle bearing highly coordinate selenium.
[structure: see text]. The first tetracoordinate 1lambda4,2-selenazetidines were synthesized by taking advantage of the Martin ligand and characterized by X-ray crystallographic analysis. The selenazetidines gave the corresponding aziridine and the cyclic selenenate on their thermolysis, which indicates the possibility that a highly coordinate 1,2-heterachalcogenetane may provide the corresponding heteracyclopropane regardless of the heteroatoms.
