Hydrogen bonded molecular complexes of cyclic carboxyaryl sulfonium salts with chlorides: syntheses and molecular structures

Abstract

Intermediates of spirosulfurane formations are prepared from carboxyaryl sulfides with chlorinating agent; the molecular structures determined by X-ray diffraction show disorted trigonal bipyramidal geometry about the sulfur atom with S⁺⋯ O, S⁺⋯ Cl^– and O–H ⋯ Cl^– interactions.
