Hydrosilylation of C−C Multiple Bonds Using (Me3Si)3SiH in Water. Comparative Study of the Radical Initiation Step
(Universidad de Belgrano - Facultad de Ciencias Exactas y Naturales - Proyectos de Investigación, 2009)
The classical radical-based hydrosilylation reaction of organic compounds bearing C−C multiple bonds is usually carried out in organic solvents and is herein presented in water with both organic solvent-soluble and ...
Zirconia-Porcelain Bonding: Effect of Multiple Firings on Microtensile Bond Strength
(Quintessence Publishing Co Inc, 2013-01-01)
Purpose: To determine the bond strength between zirconia and porcelain with varying numbers of veneer firing cycles.Materials and Methods: Fifty specimens of zirconia veneered with feldspathic ceramic were submitted to one ...
Hydrogenation of Multiple Bonds by Geminal Aminoborane-Based Frustrated Lewis Pairs
(Wiley-VCH, 2018-06-21)
The hydrogenation reaction of multiple bonds that is mediated by geminal aminoborane-based frustrated Lewis pairs (FLPs) has been explored by means of density functional theory calculations. It was found that the release ...

Photocatalytic Difluoromethylation Reactions of Aromatic Compounds and Aliphatic Multiple C-C Bonds
(Molecular Diversity Preservation International, 2019-12)
Among the realm of visible light photocatalytic transformations, late-stagedifluoromethylation reactions (introduction of difluoromethyl groups in the last stages of syntheticprotocols) have played relevant roles as the ...
Different radical initiation techniques of hydrosilylation reactions of multiple bonds in water: thermal and photochemical initiation
(Wiley, 2010-10)
The classical radical-based hydrosilylation reaction of organic compounds bearing C[BOND]C multiple bonds is usually carried out in organic solvents and is herein presented in water with both hydrophobic and hydrophilic ...
Bond strengths, degree of conversion of the cement and molecular structure of the adhesive-dentine joint in fibre post restorations
(Elsevier B.V., 2012-04-01)
Objectives: Because fibre post restorations are influenced by multiple factors such as the types of bonding materials, the dentine region and the time under moist exposure, this study sought to determine the bond strength ...
A study about regioisomeric hydroquinones with multiple intramolecular hydrogen bonding
(MDPI AG, 2017)
A theoretical exploration about hydrogen bonding in a series of synthetic regioisomeric antitumor tricyclic hydroquinones is presented. The stabilization energy for the intramolecular hydrogen bond (IHB) formation in four ...
