Facile Synthesis of Koser`s Reagent and Derivatives from Iodine or Aryl Iodides
(AMER CHEMICAL SOC, 2010)
The first one-pot synthesis of neutral and electron-rich [hydroxy(tosyloxy)iodo]arenes (HTIBs) from iodine and arenes is presented, thereby avoiding the need for expensive iodine(III) precursors. A large set of including ...
Synthesis of N-aryl imidazoles catalyzed by copper nanoparticles on nanosized silica-coated maghemite
(Elsevier, 2014-04-05)
A magnetically recoverable catalyst consisting of copper nanoparticles (CuNPs) on nanosized silicacoated maghemite is presented. The catalyst has been prepared under mild conditions by mixing the magnetic support with a ...
High Surface Area CeO2 Promoted Suzuki-Miyaura Cross-Coupling of Arylboronic Acids and Aryl Iodides
(Georg Thieme Verlag Kg, 2013-02)
High surface area cerium oxide (240 m2/g) efficiently promoted the Suzuki-Miyaura cross-coupling of aryl iodides with arylboronic acids, in the absence of palladium or any other transition metal catalyst. Excellent selectivity ...
Reactivity of 2-aryl-1,3-dithiane anions towards neopentyl, neophyl and phenyl iodides. New evidence for an SRN1 mechanism
(John Wiley & Sons Ltd, 2011-12)
The reactions of 2-(4-Z-phenyl)-1,3-dithiane anions (Z=H, OMe, Cl, CN) with neopentyl, neophyl and phenyl iodides were studied in DMSO, taking into consideration the effect of the Z substituent on the dithiane anions ...
Síntese e caracterização de iodetos de diteluroéteres - análise da estrutura supramolecular
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2012-02-28)
This work describes the synthesis and characterization of thirteen new compounds belonging to the class of ditelluroethers iodides. The starting materials (ditelluroethers) were synthesized by a method few mentioned in the ...
Suzuki–Miyaura cross-coupling of aryl iodides and phenylboronic acid over palladium-free CeO2 catalysts
(Elsevier Science, 2014-07)
The Suzuki–Miyaura cross-coupling reaction between p-iodotoluene and phenylboronic acid is carried out over a series of ceria catalysts, at 150 °C, under N2 atmosphere, employing DMF as the solvent. The ceria catalysts ...
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 ...
