Condensed heterocycles. 40. The structure of 2- and 3-benzo[b]thiophenaldehydes and their imines containing a hydrosulfide or hydroselenide group in the adjacent position

Abstract

The structure of isomeric selenol(mercapto)aldimines of benzo[b]thiophene and the complexes formed by them was studied by the methods of IR, UV, and ESR spectroscopy and magnetic susceptibility. The influence of the structure of the exocycylic heteroatom on the structure of 2- and 3-benzo[b]thiophenaldehydes containing OH, SH, or SeH groups in the adjacent position, in contrast to their imines, was demonstrated. An analogous change in the nature of the exocyclic heteroatom in complex compounds of selenol(mercapto)aldimines also does not lead to any change in the flat structure of the coordination unit in these complexes.
