Nanospheres caped Pt(II) and Pt (IV): synthesis and evaluation as antimicrobial and Antifungal Agent

Abstract

Antimicrobial and antifungal polymers are gaining the attention of pharmaceutical makers and industrial design. Nanospheres-Polymers attached Platinum(II) / (IV) complexes have been synthesized to investigate antimicrobial activities. Firstly, nanospheres involving Schiff bases were synthesized from (aminomethyl) polystyrene and four substitute salicylaldehyde (2-hydroxy benzaldehyde, 5-fluoro-2-hydroxy benzaldehyde, 5-kloro-2-hydroxy benzaldehyde, 5-bromo-2-hydroxy benzaldehyde). Secondly, polymers attached Platinum(II) / (IV) complexes have been prepared by means of template method. The IR spectra show that the ligands act in a monovalent bidentate fashion all nanospheres involving Schiff bases. Square-planar and octahedral structures are proposed for Pt(II) and Pt(IV), respectively. All these substances have been examined for antibacterial activity against pathogenic strains, and antifungal activity. In particular, Pt(IV) complexes were more potent bactericides than all of the synthesized substances.

Co(Salen) Catalysed Oxidation of Synthetic Lignin-Like Polymer: Naoh Effects

Abstract An attempt has been made to selectively oxidise synthetic lignin-like polymer for fine chemicals. The G- and S-type polymers (G- and S- type lignin model polymers) were synthesized using simple aromatic compounds as starting materials and then oxidised to benzaldehydes by reacting them with Co(salen) catalytic system. The reaction was characterized by measuring the change of the polymer with FTIR, C-13 NMR and GC-MS spectroscopy. The results obtained by the FTIR and C-13 NMR showed that the effects of NaOH were important and higher yield of benzaldehydes characterized by GC-MS in the presence of NaOH in the course of catalytic oxidation of the polymer demonstrated these effects. From the results, the catalyst could suitably be used in green procedures for lignin transformation.

Fly-ash:H2O Assisted Aldol Condensation: Effect of Solvents on the Synthesis of Some Aryl (E) 2-propen-1-ones

Abstract

Some series of aryl (E) 2-propen-1-ones have been synthesized by Fly-ash:H2O catalyzed aldol condensation of aryl methyl ketones and substituted benzaldehydes at reflux condition in atmospheric pressure. The yields of chalcones are higher than 60%. These chalcones were characterized by their physical constants and spectral data, for known compounds their purities were checked with the physical constants and spectral data earlier published in the literature. The effects of solvents on the product have been studied.

Perchloric acid catalyzed condensation of amine and aldehydes: Synthesis and antibacterial activities of some aryl (E)-imines

Abstract

A series of Schiff’s bases (aryl E-imines) have been derived from the perchloric acid catalyzed condensation of aryl amines and substituted benzaldehydes. The yield of the Schiff’s bases are more than 80%. The synthesized Schiff’s bases are characterized by their physical constants, analytical and spectroscopical data. The antibacterial activities of these Schiff’s bases have been studied using Bauer-Kirby method.
