摘要：

2-Pyridyl 2-thienyl sulfoxide was found to react with variously substituted 2-thienyllithiums and 2-selenophenyllithium, exclusively affording 2-(2-pyridyl)thiophenes and 2-(2-pyridyl)-selenophene and the disulfides derived from the substituted thiophenes and selenophene. Apparently, ligand exchange precedes ligand coupling. The coupling product always involved the pyridine nucleus, but no bithienyl-type products were formed.
