Abstract

The results of studying the reaction behavior of tungsten hexachloride toward organic iso(thio)cyanates and their combinations with nitriles are generalized. The factors determining the multiplet insertion of iso(thio)cyanates at the W–Cl bond and the conditions of symmetrical or asymmetrical crosslinking of the inserted fragments into heterocycles upon their trimerization (on the basis of the X-ray structural data on the products of the partial or complete hydrolysis of the complexes) are discussed. The reasons determining the direction of the combined insertion of heterocumulenes and nitriles at the W–Cl or W–N bond are considered, which is important for the targeted design of complexes of various architecture and new poorly accessible related heterocyclic compounds.
