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 ...
Heck, Sonogashira, and Hiyama Reactions Catalyzed by Palladium Nanoparticles Stabilized by Tris-Imidazolium Salt
(Wiley VCH Verlag, 2014-04)
Palladium nanoparticles, prepared by the hydrogenation of Pd(dba)2 in the presence of a tris-imidazolium iodide as stabilizer, act as an efficient catalyst for Heck and copper-free Sonogashira reactions with a range of ...
Active-iron-promoted hydrodehalogenation of organic halides
(Elsevier Science, 2006-09-25)
Under very mild reaction conditions, the active-iron-based reducing system composed of FeCl2·4H2O, an excess of lithium powder and a catalytic amount (5 mol%) of 4,4′-di-tert-butylbiphenyl (DTBB) as electron carrier, ...
Anions involved in the initiation of the thermally induced SRN1 reaction for α-arylation of ketones
(Royal Society of Chemistry, 2017-06)
The SRN1 reaction between acetophenone enolate and PhI is thermally induced and accelerated by microwave irradiation to give the corresponding substitution product 1,2-diphenylethanone in a 50% yield in DMSO at 70 °C. ...
Highly efficient palladium-catalyzed arsination. Synthesis of a biphenyl arsine ligand and its application to obtain perfluoroalkylarsines
(American Chemical Society, 2009-12)
An efficient one-pot, two-step Pd-catalyzed arsination with n-Bu 3SnAsPh2 (1) and sterically hindered aryl iodides (ArI) with different functional groups is reported. The cross-coupling reactions of this stannane with ArI ...
New atropisomers derived from amidinoquinoxaline N-oxides: Synthesis and NMR characterization
(Elsevier Science, 2010-10)
The complete 1H and 13C NMR characterization of some representative examples of five and six-membered amidinoquinoxaline N-oxides 1 with dissymmetric aryl substituents and their methiodides 2 is reported. Compounds 1 were ...
Substitution reactions between arenethiolate anions and 1,3-dihalo-2,2-dimethylpropanes. Synthetic scope and mechanistic aspects
(Arkat USA, 2011-03)
The synthetic scope of the reactions between benzenethiolate, 4-methoxybenzenethiolate, 2-naphthalenethiolate, and 2-pyridinethiolate anions with 1,3-dihalo-2,2-dimethylpropane was studied. These reactions render mono and ...
Synthesis of biphenyl-based arsine ligands by Suzuki-Miyaura coupling and their application to Pd-catalyzed arsination
(Royal Society of Chemistry, 2011-09)
A versatile and efficient approach for the synthesis of new biphenyl-based arsine ligands, by a Pd-catalyzed arsination to introduce the -AsPh2 moiety, and then a Suzuki-Miyaura cross-coupling for biaryl construction is ...
Unexpected formation of 4,4-dimethyl-1,2-disubstituted-dicarbonyl cyclopentanes from ketone enolate anions and 1,3-diiodo-2,2-dimethylpropane
(Royal Society of Chemistry, 2016-03-07)
Cyclic 1,4-dicarbonyl compounds can be easily obtained by mixing a solution of aryl methyl or alkyl methyl ketone enolate anions with 1,3-diiodo-2,2-dimethylpropane in DMSO. This represents the first example of dimerization ...
