obtain basic knowledge on the complexes of La(III) with some symmetric 1,5-diaryl-3-cyanoformazans. The ionization constants of the formazans as well as the formation constants of their lanthanum complexes were studied potentiometrically m solution by Sarin's method. The La(III) complexes formed were separated and their structures were elucidated by elemental analysis, IR, NMR spectroscopy, thermogravimetry

The synthesis of heterocyclic azo-dyes via conventional heating and microwave (MW) heating was investigated. From a sequence of reactions starting from cyanoacetic acid, 4-arylazo-2H-pyrazol-3-ylamines and 4-arylazo-2-phenyl-2H-pyrazol-3-ylamines were obtained. The structures these compounds were obtained by inspection of spectroscopic and analytical techniques including 1H and 13C NMR spectroscopy
