Chemistry of Heterocyclic Compounds Aims and scope

Abstract

The perchlorates of 2,6-di(2-thiettyl)-4-methylpyrilium and -thiopyrilium, and the isomeric 2,4-di(2-thienyl)-6-methyl derivatives, as well as the perchlorates of 2,4-di(2-thienyl)pyriliurn with tri- and tetramethyl groups in the 5,6 position have been synthesized. Their UV and PMR spectra have been studied. Based on data on Oberhauser's nuclear effect it was concluded that the sulfur atoms of 2(6)-thienyl substituents and the O(S) atoms of heteroaromatic cations are present in the cis position.
