Benzothiazolylazo derivatives of some β-dicarbonyl compounds and their Cu(II), Ni(II) and Zn(II) complexes [PDF]

open access: yesJournal of the Serbian Chemical Society, 2010
The coupling of diazotized 2-aminobenzothiazole with 1,3-dicar-bonyl compounds (benzoylacetone, methyl acetoacetate and acetoacetanilide) yielded a new series of tridentate ligand systems (HL).

Synthesis, spectroscopic characterization, computational and electrochemical studies of sulfamethazine based azo dyes

open access: yesResults in Chemistry
Present work describes the synthesis of heterocyclic azo dyes derived from sulfamethazine. The dyes were synthesized by the diazotization of sulfamethazine and coupling reactions with four coupling compounds - barbituric acid, thiobarbituric acid ...
