Radical Arylations
(John Wiley & Sons Ltd, 2012)
This chapter reports on radical arylations also highlighting the very important early achievements on this chemistry. To be named at this place are the Meerwein arylation and the Pschorr reaction. Intramolecular homolytic ...
Radical Based Arylation Methods
(Wiley, 2009)
Most of the radical reactions can be conducted under mild conditions. In contrast to ionic reactions and many transition-metal mediated processes most of the functional groups are tolerated under radical conditions. Moreover, ...
Synthesis of novel biaryl derivatives of sesamol (5-Benzodioxolol) and evaluation of their antioxidant activity against DPPH radical
(Csiro Publishing, 2013-08)
A simple and direct arylation of sesamol with aryl halides by a photoinduced reaction is reported. Five 6-arylsesamol derivatives were synthesized in order to evaluate possible changes in their antioxidant properties as a ...
A different route to 3-aryl-4-hydroxycoumarins
(Pergamon-Elsevier Science Ltd, 2010-10)
We herein report the simple and direct arylation of 4-hydroxycoumarins by photoinduced reaction with aryl halides (iodobenzene, iodonaphthalene, 4-iodoanisole, 2-iodoanisole). Good yields of 3,4-disubstituted coumarins ...
Synthesis of triaryls: hydroxy and amine dinaphthyl anddiphenanthryl aryls by one-pot electron-transfer nucleophilicsubstitution reactions
(Pergamon-Elsevier Science Ltd., 2014-01)
A new one-pot synthetic route to achieve the preparation of hydroxy and amine binaphthyl and biphenanthryl aryls is here reported. This approach involves the reaction of 1,4-bromoiodobenzene, 4,4′-diiodobiphenyl, and 1,4- ...
Microwave role in the thermally induced SRN1 reaction for a-arylation of ketones
(The Royal Society of Chemistry, 2015-02)
The coupling between iodobenzene and the enolate anion of acetophenone is accelerated by microwave irradiation. This increase in reaction rate is only ascribed to thermal effects. The coupling reaction gave the corresponding ...
Anthraquinones as Photoredox Catalysts for the Reductive Activation of Aryl Halides
(Wiley VCH Verlag, 2018-01)
Quinones are ubiquitous in nature as structural motifs in natural products and redox mediators in biological electron-transfer processes. Although their oxidation properties have already been used widely in chemical and ...
Competitive reaction pathways for o-Anilide aryl radicals: 1,5-Or 1,6-hydrogen transfer versus nucleophilic coupling reactions. A novel rearrangement to afford an amidyl Radical
(American Chemical Society, 2009-02)
The photoinduced reactions of o-iodoanilides (o-IC6H 4N(Me)COR, 4a-d) with sulfur nucleophiles such as thiourea anion (1, -SCNH(NH2)), thioacetate anion (2, MeCOS-), and sulfide anion (3,S2-) follow different reaction ...
Tuning Aryl, Hydrazine Radical Cation Electronic Interactions Using Substitutent Effects
(Journal of Physical Chemistry A, 2013-01-16)
1,4-Dihydropyridines: Reactivity of nitrosoaryl and nitroaryl derivatives with alkylperoxyl radicals and ABTS radical cation
(TAYLOR & FRANCIS, 2004-07)
In the present paper, a direct quenching of radical species by a number of synthesized nitrosoaryl 1,4-dihydropyridines and their parent nitroaryl 1,4-dihydropyridines was determined in aqueous media at pH 7.4. These two ...
