Synthesis and insecticidal activity of bis 4, 4-[2-substituted aryl thiazolidine-4-one] diphenyl sulphone

A series of thiazolidine-4-one have been synthesized by condensation of 4, 4-diaminodiphenyi sulphone with four different substituted aromatic aldehydes to yield the Schiff s bases. Cyclocondensation of Schiff s bases with thioglycolic acid afforded Bis 4, 4-[2-substituted aryl thiazolidine-4-one] diphenyi sulphone. The structure of newly synthesized compounds were confirmed using analytical and spectral [IR and PNMR] data. All these compounds were evaluated for their insecticidal activity. All four compounds have equipotent insecticidal activity with the standard drug Cypermethrin
