Abstract
|
Cobalt tetra-2,3-pyridiniumporphyrazinato with sulfonic acid tag [Co(TPPASO3H)]Cl was produced and catalyzed the synthesis of ortho-aminocarbonitriles, cyclohexa-1,3-dienamines and 2-amino-3- cyanopyridines. The synthesis of 2-amino-3-cyanopyridines by using [Co(TPPASO3H)]Cl proceeded via a cooperative vinylogous anomeric based oxidation mechanism. [Co(TPPASO3H)]Cl can be recycled and reused six times with a marginal decreasing of its catalytic activity.
