Aromatic stabilization of organochalcogen compounds with the intramolecular X←O (X = S, Se, Te) coordination
Abstract
The ab initio MP2/LanL2DZ calculations predict a significant contribution of cyclic π-electron delocalization to the stabilization of the trans-cis-cis conformation of derivatives of β-chalcogenovinylaldehydes 1 with the intramolecular Chalc←O coordination.
