[4 + 3] and [4 + 2] mechanisms of the Diels-Alder reactions of vinylboranes: an analysis of the electron charge density distribution
(Royal Society of Chemistry, 2013-09)
The Diels-Alder (DA) reactions of isoprene with vinylborane, dimethylvinylborane and dichlorovinylborane have been studied using density functional theory and the quantum theory of atoms in molecules. We evaluated the ...
The role of polyprenol-bound saccharides as intermediates in glycoprotein synthesis in liver
(National Academy of Sciences, 1972-11)
It has been reported that liver microsomes catalyze the transfer of glucose from uridine diphosphate glucose to dolichol monophosphate so as to produce dolichol monophosphate glucose. Dolichol is a polyprenol containing ...

High-Energy Dissipation Performance in Epoxy Coatings by the Synergistic Effec of Carbon Nanotube/Block Copolymer Conjugate
(American Chemical Society, 2017-01)
Hierarchical assembly of hard/soft nanoparticles holds great potential as reinforcements for polymer nanocomposites with tailored properties. Here, we present a facile strategy to integrate polystyrene-grafted carbon ...
Cycloaddition Reactions Assisted by Microwave Irradiation: Protic Ionic liquids vs Solvent-free Conditions
(Betham, 2017-09)
Background: The behavior of N-tosylnitroindoles acting as electrophilic dienophiles in polar Diels-Alder reactions joint to different dienes was analyzed. Reactions were developed under microwave irradiation using toluene ...
Thermal behavior, reaction pathways and kinetic implications of using a Ni/SiO2 catalyst for waste tire pyrolysis
(Springer, 2021-06-06)
Catalytic pyrolysis has been used to upgrading the quality of pyrolytic liquids. Herein, we report a comprehensive study on the catalytic pyrolysis of waste tires using Ni/SiO2 as catalysts. The analyses were carried out ...
