Two series of 1,n-alkylene glycol di [4{N(T-thiazolylazoÂ
nrethinyl)}2-metho y] phenyl ether and I ,n-alkylene glycol di[4{N(r-benzo-thiazolylazomethinyl)}2-methoxy]phenyl ether were synthesize-d via rea tions 2-aminothiazole and 2-aminobenzothiazole with dialdehyde • (which are synthesized from .reaction vanil.lin with
l ,n-dibromo or ehloro. alkane in the basic me'dia ) . The new
compounds characterized by elemental analysis (of some of theme) , physical and spectral data .All the schiff-bases have been screened for their antifungal and antibacterial activity against Aspergillus niger ,. Escherichi coli (0-) and Staphylococcus aureus . (G+) . AlJ compounds were found to be active antibacterial and antifungal (except [III] 12 was not show any antifungal activity).
