Catalyst- and solvent-free hydrophosphination and multicomponent hydrothiophosphination of alkenes and alkynes
(Royal Society of Chemistry, 2016-05-26)
The hydrophosphination of carbon-carbon multiple bonds has been generally performed under acid, base or metal catalysis in different solvents. Herein, alkyl and alkenyl tertiary phosphines are obtained by the addition of ...
Wells-Dawson type catalyst: An efficient, recoverable, and reusable solid acid catalyst for the solvent-free synthesis of benzodiazepines
(Bentham Science Publishers, 2014-03)
Various 3-H-1,5-benzodiazepines were prepared from the solvent-free reaction of o-phenylenediamine and substituted 1,3-diphenyl-1,3-propanedione, giving good yields of benzodiazepines. The H6P2W18O62.24H2O solid heteropolyacid, ...
Green and efficient synthesis of flavones and chromones using heteropolyacids as catalyst in glycerol
(Bentham Science Publishers, 2018-04-22)
Organic solvents are required to carry out most organic transformations, which cause environmental pollution because of their low volatility. Glycerol, a side product obtained from biodiesel production, has emerged as a ...
Cyclohexene and cycloodene epoxidation with aqueous hydrogen peroxide using transition metal-free sol-gel alumina as catalyst
(Wiley-v C H Verlag GmbhWeinheimAlemanha, 2004)
Alumina: a cheap, active and selective catalyst for epoxidations with (aqueous) hydrogen peroxide

Green Synthesis of a Cu/SiO2 Catalyst for Efficient H2-SCR of NO
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-09)
In this work, the synthesis of Cu/SiO2 catalysts starting from pre-formed copper nanoparticle (CuNP) colloidal suspensions was carried out. Two different protocols for the CuNP synthesis were tested: (i) a green approach ...
Nickel alpha-Keto-beta-Diimine Initiators for Olefin Polymerization
(WILEY-V C H VERLAG GMBH, 2009)
(Figure Presented) A new ligand-metal combination (see picture, Ni green, Br brown, N blue, O red, C gray) was designed to be cationic and to benefit from removal of electron density by the action of a Lewis acid on the ...
A Green Synthesized SnO2 Photo-Catalyst for Effective Degradation of Biomedical Industrial Waste
(Trans Tech Publications Ltd, 2022)
Using a green synthesis approach, we have synthesized SnO2 nanoparticles. The morphology of the nanoparticles are characterise by scanning electron microscopy. The UV-vis spectroscopy technique was used to study the optical ...
