Cobalt complexes of redox noninnocent azo-aromatic pincers. Isolation, characterization, and application as catalysts for the synthesis of quinazolin-4(3H)-ones

Herein we report synthesis and characterization of three new cobalt(ii)-complexes of redox noninnocent arylazo ligands and unveil their catalytic application towards the synthesis of a variety of substituted quinazolin-4(3H)-ones.
