Abstract
p-Bis(4-thiazolidinon-3-yl)phenylenes were synthesized from cycloaddition of thioglycollic acid with schiff bases of p-phenylenediamine or by treatment of p-bis(thiouredo)phenylenes with ethyl chloroacetate. The effect of hydrazines, hydroxylamine, acetamidine and N-phenylthiourea on p-bis(arylidenethiazo- arylidenethiazolidinon-3-yl)phenylenes IIb and IV have been reported. Some of the newely compounds were subjected under biological tests.
