SYNTHESIS OF FUNCTIONALLY SUBSTITUTED PYRIDINES AND DIPYRIDYL-SUBSTITUTED COMPOUNDS WITH THE AID OF LOW-VALENCE COMPOLEXES

Article abstract of DOI:10.1007/BF00515642

The possibility of the preparation of oxygen, nitrogen, and sulfur-containing pyridines and dipyridyl-substituted compounds by the cyclocotrimerization of substituted propionitriles with acetylene under the influence of a Co(2-ethylhexanoate)2-Al(C2H5)3 catalyst was demonstrated.It was established that the nature of the heteroatom in substituted propionitriles has virtually no effect on the direction of the reaction.
