Abstract:
A novel mechanically stable supramolecular Co(ii)-metallohydrogel has been synthesized. Cobalt(ii) nitrate hexahydrate and monoethanolamine, as a low molecular weight organic gelator, are used to get the gel. The mechanical stability of the supramolecular hydrogel was analyzed. The morphology of the supramolecular metallohydrogel was scrutinized. The semiconducting features of the metallohydrogel were studied. The conducting properties of the Co(ii)-metallohydrogel establish a Schottky barrier diode type nature. The catalytic nature of the Co(ii)-metallohydrogel based room temperature single pot aryl-S coupling reaction was explored. Most interestingly, the Co(ii)-metallohydrogel based catalytic aryl-S coupling reaction does not require any column-chromatographic purification protocol to get pure aryl-thioethers. Thus, through this work a semiconducting Schottky barrier diode application and catalytic role in the room temperature single pot aryl-S coupling reaction of a supramolecular Co(ii)-metallohydrogel have been explored.

02:17Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...

Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.

The formation of hydrates is a reversible reaction. Hydrate formation is influenced by steric and electronic factors accompanying the alkyl substituents on the carbonyl group: The rate of hydrate formation increases with a decrease in the number of alkyl groups attached to the carbonyl carbon. Hence,...
