A simple and versatile approach based on AuNPs-stabilized Pickering catalyst in water–chloroform biphasic medium has been developed for the synthesis of poly(alkyl/arylhydrosiloxane)s.

The self-assembly of functional polymer vesicles embedded with PdNPs at water–chloroform interfaces provides a novel catalytic route for the synthesis of poly(hydrosiloxane)s, H2RSi[OSiRH]nOSiRH2.

We successfully synthesized the Ru exchanged MMT clay with different Ru metal stacking using the wet impregnation method. All the developed materials were analyzed with advanced analytical techniques. All the data were found in good agreement with each other. Further, we tested all the catalysts for the reduction of aromatic and aliphatic nitro compounds to the corresponding amines in conventional and ionic liquid reaction mediums. We easily isolated the amines with simple ether washing (in an ionic liquid medium) and recycled the catalyst up to 8 times. We also synthesized various amines using the proposed methodology which have direct importance as a building block of several biologically active compounds.

The synthesis of 1,1,3,3-tetraorganodisiloxanes from the hydrolytic oxidation of diorganosilanes, RR1SiH2, using AuNPs as an interfacial catalyst is described. This study provides a manifestation of the photothermal effect in enhancing the catalytic activity at ambient temperature.

Introduction: In this work, we have successfully synthesized four types of ionic liquid-mediated Pd nanocatalysts and performed the physiochemical analysis of the developed Pd-based nanocatalysts using a transmission electron microscope (TEM), X-Ray diffraction analysis (XRD), X-ray photoelectron spectroscopy (XPS), and atomic absorption spectroscopy (AAS) analysis. Method: The well-dispersed and fine Pd nanoparticles were recorded in the ILPdNPs-4 catalytic system. We used this catalytic system to reduce a series of aliphatic and aromatic compounds with nitro groups and developed various biologically active amine molecules. In the continuation of the same, we also reduced nitrolactone, which is considered one of the important starting materials for the synthesis of renin inhibitor aliskiren (Tekturna®, and worldwide as Rasilez®). Result: We also completed the catalyst stability test and recycled the ILPdNPs-4 catalytic system for up to eight runs. Conclusion: No sign of metal leaching, Pd black formation, and agglomeration was recorded during recycling runs.
