The relevance of the nuclearity of the metal in the cocyclization of α,ω-diynes and nitriles catalyzed by mesitiylene solvated cobalt atoms; preliminary EPR studies

The clustering when mesitylene-solvated cobalt atoms are allowed to warm from the cocondensation temperature, affords cobalt compounds of both low and high nuclearity which have different catalytic properties in the synthesis of pyridines from α,ω-dialkynes and nitriles.
