Opis:
Benzimidazole derivatives have been synthesized by solid Nanocatalysts Zirconia and Sulfated Zirconia with Green reusablity method. Synthesis of benzimidazole was carried out by conventional as well as microwave method. Synthesis carried out by reacting o-phenylenediamine and few aldehydes in the presence of catalytic amount of Nanoparticles. Particles used were sized in between 53-100 nm. Nanoparticles and synthesized benzimidazole derivatives were characterized by DLS, powder XRD, SEM-EDX andMass, CHNS, FT-IR, NMR analysis respectively.

Opis:
2-(chloromethyl)-5-(4-nitrophenyl)-1,3,4-oxadiazole was synthesized via reaction of chloroacetic acid with 4-nitrobenzohydrazide in phosphonyl chloride(4). Compound 4 was treated with 4-aminophenol to form 4-((5-(4-nitrophenyl)-1,3,4-oxadiazol-2-yl)methoxy)aniline(5) having free -NH2 group,which is reacted with chloroacetyl chloride to give 2-chloro-N-(4-((5-(4-nitrophenyl)-1,3,4-oxadiazol-2-yl)methoxy)phenyl)acetamide(6). Compound 6 was cyclized by ammonium thiocyanate to form 2-((4-((5-(4-nitrophenyl)-1,3,4-oxadiazol-2-yl)methoxy)phenyl)amino)thiazol-4(5H)-one(7) with thiazolone ring. Compound was reacted different aldehydes to form (E)-5-benzylidene -2-((4-((5-(4-nitrophenyl)-1,3,4-oxadiazol-2-yl) methoxy)phenyl) amino)thiazol-4(5H)-one derivatives(8a-j). In vitro antibacterial activity of the target compounds were investigated using two types of bacteria, Staphylococcus aureus (Gram-positive) and Escherichia coli (Gram-negative). The results indicated that the newly synthesized (E)-5-benzylidene-2-((4-((5-(4-nitrophenyl)-1,3,4-oxadiazol-2-yl)methoxy) phenyl)amino)thiazol-4(5H)-one derivatives (compounds 8d and 8f) showed enhanced activity against Gram-negative bacteria when compared with that of the control drug (gentamycin).

Opis:
N,N,O-Tridentate ligands were prepared by the condensation of 1-(Benzothiazole 2-yl) hydrazine with substituted salicyldehydes or different aromatic ketones. New synthesized metal complex are thermally stable and neither air- nor moisture-sensitive. Suzuki–Miyaura cross-coupling reaction is carried out in present of various ligands and palladium salts, Different solvent/water ratio with different Base and studied effects its effect on the performance of the coupling reaction.
