Application of GO's intrinsic catalytic abilities is limited to either hydration or oxidation of various organic compounds, including alcohols, alkynes, and alkenes34. Additionally, the use of heteroatom doped GO in oxygen reduction reactions is considered as a natural use of GO's catalytic ...
The zeta potential and size distribution values increased as the quantity of L. rhamnosus bioactive metabolites increased in the chitosan nanoparticles. The FTIR analysis indicated the presence of several functional groups, including alkynes, alkene, aliphatic primary amines, and other functional groups. ...
processes for the addition of hydrogen halides to alkynes. One is a mixed phase reaction wherein copper (I)-chloride is the catalyst. In the other, the alkyne is vaporized and mixed with hydrogen chloride and passed over activated charcoal in the presence of mercury at a temperature of 130...
In some embodiments, the alkylation reactive center or group of a target compound can be a suitable nucleophile for an alkylation reaction. Examples of alkylation reactive centers include but are not limited to a N, O, S, P, C, aldehydes, aliphatic carbons, alkanes, alkenes, alkynes, alcohols...
