Abstract

A number of diazo coupled products of chromium(III) chelates of acetylacetone and benzoylacetone were prepared by using some aryl diazonium ions. The aryl diazonium ions of 4-chloro, 4-bromo, 2,5-dimethoxy, 4-nitro and 1-naphthyl were synthesized by diazotization of respective aniline groups. The prepared diazo coupled products were characterized on the basis of their analytical data, magnetic moment, 1H NMR spectra, molar conductance, infrared and electronic spectral studies. Considering all these data, the structures of the synthesized diazo coupled products of chromium (III) were proposed to be octahedral.

 

Key words: β-diketone, electrophilic substitution, diazocoupled products, chelates.
