The oxidation of some para -substituted benzhydrols by benzimidazolium dichromate (BIDC) in dimethyl sulfoxide (DMSO) medium, results in the formation of corresponding diphenyl ketone. The reaction has been investigated on the condition of pseudo-first order . In terms of both BIDC and hydrogen-ion, the reaction is first order. In the case of benzhydrols, however, Michaelis-Menten type kinetics is observed. At different temperatures, the formation constants and rates of breakdown of benzhydrol-BIDC complexes have been determined. Complex formation thermodynamic parameters and activation parameters for complex decomposition have been computed. The kinetic isotope effect found in the oxidation of benzhydrol (( k H / k D = 5.93 at 293 K) shows that the rate-determining step involved α -C-H bond fission. For the kinetic analysis of the reaction, nineteen organic solvents have been utilized. The solvent impact have been investigated, and found that cation-solvation plays a significant role. A suitable mechanism is proposed based on the kinetic data, solvent effect analysis, and results of various non-kinetic parameters.

In an attempt to design a potent class of antimicrobials, we have synthesized benzimidazole derivatives based on 4-thiazolidinone which possessed 5-arylidenes 5a-o by using different catalysts under multistep conventional synthesis. Structures of the synthesized compounds have been established based on spectral data and compounds have been screened for their antimicrobial activity. Compound 5j shows maximum potency against all Gram-positive bacteria with a minimum inhibitory concentration (MIC) in the range of 25-50 μg/mL while moderate activity against Gram-negative bacterial strains is observed with a MIC value of 62.50 μg/mL. Compound 5n is found to be the most active against fungal strains with a MIC value of 250 μg/mL.

In the present study, novel quinoline substituted pyrimidine heterocyclic azo dye derivatives ( IVa-x ) have been synthesized. All the prepared compounds have been characterized by several spectroscopic analyses and evaluated for in vitro antimicrobial activity. Furthermore, the dyeing performances of all the compounds have been estimated on cotton and silk fabrics. Colour and rubbing fastness properties of all the dyed fabrics have been examined by referencing to standard gray scale. These newly synthesized azo dyes exhibit various hues with good to excellent fastness properties. Out of all the phenol derivatives, Naphthol substituted compounds have come out as remarkably active antimicrobial scaffolds with excellent dye characteristics.
