Azo Coupling


Recent Literature


Unsymmetrical and symmetrical bis(hetaryl)azo dyes were prepared by diazotisation-coupling and oxidation reactions in moderate yields. Their absorption maxima were observed in the range of 427-631 nm, being more bathochromic than the corresponding non-hetarylazo derivatives.

A green dehydrogenation of hydrazo compounds using basic alumina or KF/alumina under solvent-free conditions afforded azo compounds in good to excellent yields.
