Abstract Innovations in water technology are needed to solve challenges of climate change, resource shortages, emerging contaminants, urbanization, sustainable development and demographic changes. In particular, conventional techniques wastewater treatment limited by the presence poorly biodegradable organic matter. Alternatively, recent Fenton, Fenton-like hybrid processes appear successful fo...
Summarization of electronic discussion fora is a unique challenge; techniques that work startlingly well on monolithic documents tend to fare poorly in this informal setting. Additionally, conventional techniques ignore much of the structures that have the potential to serve as valuable features in the summarization task. We present several novel examples of such features, including the catalys...
Abstract Suzuki coupling is a widely used, well-studied and versatile method in synthetic chemistry for development of C–C bonds where palladium-based catalysts have been used extensively the reaction to date. We report Suzuki-cross-coupling formation between aryl halides phenylboronic acid by using Metal/metal oxide@Reduced graphene oxide nanocomposites being efficient, simple cost-effective. ...
[reaction: see text] A useful method for the conversion of prochiral allylic alcohols to chiral allylic amines of high enantiopurity is reported. N-(4-Methoxyphenyl)trifluoroacetimidates are excellent substrates for the palladium(II)-catalyzed allylic imidate rearrangement as the allylic trifluoroacetamide products can be deprotected in two steps to provide chiral nonracemic allylic amines. Di-...
