coupled reaction

[′kəp·əld rē′ak·shən]
(chemistry)
A reaction which involves two oxidants with a single reductant, where one reaction taken alone would be thermodynamically unfavorable.

2a-e, it could be observed that a depletion hole formed and grew to a width with 40 nm apparently from 0 to 24 h, which was a direct evidence of DC coupling reaction at the interface.
Palladium catalyzed coupling reactions using water-soluble phosphine ligands: DTBPPS and DAPPS and their ability to promote coupling reactions.
Recently, a planar interface, which excludes the complex effect of shearing and elongational flows on the reactive compatibilization, was used to reveal the coupling reaction between polymer interfaces.

Coupling reactions between vinyl or hydroxy functional groups and hydrosilane are faster than polymerization of the latter.
In this work, three novel vinylsulfone based azo reactive dyes were successfully synthesized by successive condensations, diazotization and coupling reaction steps using reactive acids i.e.
The reaction between PMDA and recycled PET can be categorized into three possible types: (a) blocking reaction, which means a PMDA molecule joins one PET molecule, (b) coupling reaction, which comes after the blocking reaction when a PMDA molecule joins two molecules of PET linearly, and (c) branching reactions, in which PMDA molecules join more than 2 PET molecules and/or more than one PMDA molecule joins more than two PET molecules, which leads to crosslinking and later to gel formation.
"Chapter 1: Synthesis and Preparation of Nanomaterials," reflects work done in: nanoimprinting lithographics; palladium nanoparticles synthesized by bio-templates for Suzuki coupling reaction; preparation conditions of nano-silver substrate used for SERS determination of thiophene; synthesis and property of neutral silicone glass sealant; and the preparation and characterization of nanometer gallium nitride b gas-solid reaction, among other areas.
Summary: Reactive dyes were synthesized from cyanuric chloride and 1-amino-8-hydroxy- naphthalene-3-6-disulphonic acid by condensation diazotization activation and coupling reaction. The colorimetric properties and fastness of these dyes were measured.
Ethanol formation during the coupling reaction between silica and silane is another problem.
