Conclusions
The simultaneous cyclotrimerization process of phenylacetylene and 3-phenoxypropyne with benzonitrile has been studied in the presence of cobaltocene. An increase in the amount of nitrile in the starting material mixture increases the concentration of unsymmetrical pyridine and benzene isomers in the reaction products. 3,6- and 4,6-bis(phenoxymethyl)-2-phenylpyridines and tris(phenoxymethyl)benzenes have been prepared and characterized for the first time.
