Synthesis of new azo compounds based on thiazolidinone derivatives.

Azo compounds have been most widely used in many fields and technologies like textiles, paper, plastic, leather, ink jet printers, laser liquid crystalline displays [1-2].Some novel azo compounds based on thiazolidinone were designed and synthesized. Diazonium ions synthesis of coupling reaction between aniline derivatives and with 2-hydroxy benzaldehyde. Then from the reaction of diazonium salts whit thiosemicarbazide and diethyl acetylene dicarboxylate products containing thiazole rings were synthesized
