Chemistry of Heterocyclic Compounds Aims and scope

Abstract

Ascheme for formation of 6,6′,7,7′-tetrahydro-2,2′,4,4′-tetraaryl-8,8′-bis(5H-1-benzothiopyranyls) through intermediate radicals and cation radicals was substantiated as a result of a study of the electrochemical behavior of 2,4-diarylcylohexa[b]thiopyrylium tetrafluoroborates and 2,4-diaryl-4H-cyclohexa[b]thiopyrans and comparison with the results of their oxidative dimerization. The formation of 2,4-diarylcyclohexa[b]thiopyranyl radicals is also confirmed by EPR spectroscopy.
