1) Abstract : A Series of substituted heterocycles, 1,1–{bis-[3-hydroxy-4-1-phenyl-5(3,4-disubstitutedphenyl)-pyrazol-3-yl]-oxyphenyl}-methanes (VIII)(a-d). and 1,1 – {bis-[3-hydroxy-4-1-phenyl-5-(3,4-disubstituted phenyl)-pyrozolin-3-yl]-oxyphenyl}-methanes–(V)have been synthesized by condensation of 1,1-{bis-[3-hydroxy-4-3-(3,4-disubstitutedphenyl)–propane-2-1,3-dione]-oxyphenyl}-methanes- (VIB) and 1,1-{bis-[3-hydroxy-4-3-(3,4-disubstituted phenyl)–prop-2-ene-1-one]-oxyphenyl}- methane (II) with phenyl hydrazine hydrochloride in pyridine medium respectively. The compounds were characterized by IR and 1H NMR data. All the compounds are evaluated for their antibacterial and antifungal activity. Comparative study of these prepared bis-pyrazoles and bis-pyrazolines have been carried out in this paper.
