Electrochemical reactions of chalcogenbiscyclanones and the products of their S-, O-, and N-heterocyclization

In this work, the routes of the redox reactions of chalcogenbiscyclanones and the products of their S-, O-, N-heterocyclization in organic solvents were analyzed and validated. The influence of the nature of the heteroatoms and substituents on the redox activity of S- and Se-containing biscyclanones, benzannelated thianthrenes, oxathianthrenes, and diazepine was established based on electrochemical studies, ESR spectroscopy data, and the results of quantum chemical calculations
