Treatment of tris(2-pyridyl)phosphine or tris(2-pyridyl)phosphine oxide with electrophiles such as chlorine, bromine, deuterium chloride, or benzenediazonium chloride gave unusual coupling products, i.e., 5-chloro-, 5-bromo-, 5-deuterio-, or 5-phenylazo-2,2Πbipyridyls, respectively, as a major coupl
The reaction of 2-(2'-pyridyl)-pyridinium N-ylides with substituted ethylenes such as acrylonitrile and ethyl acrylate gave the corresponding tetrahydroindolizine derivatives in high yields. Tetrahydroindolizine derivatives were dehydrogenated by treating with tetrapyridinecobalt(II) bichromate [CoP
2-Pyridyl2-thienyl sulfoxide was found to react with variously substituted 2-thienyllithiums and 2-selenophenyllithium, exclusively affording 2-(2-pyri-dy1)thiophenes and 2-(2-pyridyl)-selenophene and the disulfides h v e d from the substituted thiophenes and selenophene. Apparently, ligand exchange
