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.

COBALT ATOMS AS CATALYSTS OF THE SYNTHESIS OF PYRIDINES FROM NITRILES AND ACETYLENES

Cobalt atoms have been found to provide efficient and selective catalysts for the synthesis of pyridines from nitriles and acetylenes; the reaction conditions are milder than those reported for other cobalt-containing catalyts.

UNEXPECTED CYCLOCOTRIMERIZATION OF α,ω-DIALKYNES AND NITRILES TO ALKYNYLPYRIDINES CATALYZED BY ARENE-SOLVATED COBALT ATOMS

Arene solvated cobalt atoms have been found to promote an unusual conversion of α,ω-dialkynes and nitriles to alkynyl-substituted pyridines.

The first cobalt catalyzed [2 + 2 + 2] alkyne cyclotrimerization in aqueous medium at room temperature

Chelate complex 1 (5 mol%) was found to catalyze the [2 + 2 + 2] cyclization of terminal alkynes in good yields in a 80/20 mixture of water and ethanol at room temperature without further activation.

Activation of Carbon Dioxide: Nickel-Catalyzed Electrochemical Carboxylation if Diynes

The simualtaneous activation of carbon dioxide and diynes by electrogenerated LNi(0) complexes (L=bpy, pentamethyldiethylenetriamine: PMDTA) enables the selective incorporation of one molecule of CO2 into the unsaturated systems and the preparative-scale
