ABSTRACT:

Various substituted azo-coumarins and schiff’s bases bearing methoxy and chloro groups have been synthesized by the condensation of substituted 3-chloro-4-methoxy phenyl azosalicylaldehyde with different malon-anilic acids by using pyridine as condensing agent. Structure of newly synthesized azo-coumarins and schiff’s bases were established on the basis of their analytical and spectral evaluation.

KEYWORDS:

Substituted phenyl azo-coumarins and Schiff’s bases; condensation; spectral studies
