Synthesis and evaluation of some chromene derivatives as antioxidant with surface activity

Abstract

A number of azo heterocyclic derivatives 3a-j were synthesized by the reaction of chromene derivative 1 with different aryl diazonium chloride 2a-j. These compounds have an increase antioxidant activity due to increasing the chromophores, which give facility for radical scavengers, and hydroperoxide decomposers, as well as synergistic mixtures of both of them. Condensation of these compounds and stearoyl chloride with propoxylated the products by using propylene oxide afforded surface active agents have a pronounced surface activity, which can be serve in the manufacture of antioxidant additives, dyes, drugsand cosmetics.
