Effect of pyridinium based ionic liquid on the sensing property of Ni0 nanoparticle for the colorimetric detection of hydrogen peroxide

In this work, we presented a new colorimetric technique for the easy and quick detection of hydrogen peroxide. Two types of ionic liquids namely imidazolium and pyridinium containing cations with an acetate anion were evaluated in this study. Ni nanoparticle is synthesized using the wet chemical method, which is further characterized using various analytical techniques. Ni nanoparticles coated with pyridinium based ionic liquid showed robust peroxidase-like activity, which resulted in better dispersion of nickel nanoparticle and is able to quickly catalyze the oxidation reaction of substrate 3,3,5,5-tetramethylbenzidine (TMB) in the presence of hydrogen peroxide (H2O2), leading to the generation of a blue-colored solution. On the basis of color development, colorimetric sensing of [Pyr]Ac- Ni0 was achieved with a detection limit (LOD) of 120 μM/L within a linear range of 400–4000 μM. The proposed method is significantly selective for [Pyr]Ac- Ni0and can be conveniently and affordably applied to the detection of hydrogen peroxide without any complicated instrumentation.

PROCESS FOR THE PREPARATION OF ILOPROST

The present invention relates to a process for the preparation of iloprost of formula I through new intermediates, isolation of iloprost of formula I in solid form, as well as preparation of the 16(S)-iloprost and 16(R)-iloprost isomers of formulae (S)-I and (R)-I and isolation of iloprost of formula I and 16(S)-iloprost of formula (S)-I in solid, crystalline form.

Tunable protic ionic liquids as solvent-catalysts for improved synthesis of multiply substituted 1,2,4-triazoles from oxadiazoles and organoamines

More than green alternatives to traditional volatile molecular organic solvents, protic ionic liquids as dual solvent-catalysts have been successfully used to promote reactions of organoamines with oxadiazoles to afford sterically hindered 1,2,4-triazoles. Among the tested protic ionic liquids, pyridinium trifluoroacetate and acetate showed the highest efficiency for the reactions of arylamines and alkylamines, respectively, indicating that tunable catalysis could be readily effected with protic ionic liquid solvent-catalysts by simply tuning their cation and anion counterparts. A general and efficient approach has been developed for synthesis of multiply substituted 1,2,4-triazoles based on the tunable protic ionic liquid solvent-catalyst systems.
