Synthesis of novel fused azaheterocycles by photostimulated intramolecular SRN1 reactions with nitrogen nucleophiles
(Elsevier, 2009-12)
The synthesis of pyrrole, indole, and pyrazole fused azaheterocycles is presented. The anions of carboxamides (6 and 12) and pyrazolylamines (15a-b) react under photostimulation by an intramolecular SRN1 process to yield ...
Recent advances in the synthesis of stannanes and the scope of theirposterior chemical transformations
(Elsevier Science Sa, 2014-01)
The SRN1 reactions of trimethylstannyl and triphenylstannyl anions, and other tin nucleophiles with haloarenes are quite versatile. Thus, the SRN1 mechanism can afford triorganylstannyl aromatic compounds which otherwise ...
Synthesis of 1,1-Bis(trimethylstannyl)cyclopropanes by the SRN1 Mechanism
(American Chemical Society, 2009-12)
The reactions of readily aVailable 1,1-dichlorocyclopropanes, obtained by addition of dichlorocarbene to alkenes, with Me3Sn- anions are reported. The process is described in terms of a photoinduced SRN1 substitution. The ...
Synthesis of pyrido[1,2-a]benzimidazoles by photo-stimulated C–N bond formation via SRN1 reactions
(Elsevier, 2013-04)
The photo-stimulated cyclization of 2-(2-halophenylamino)pyridines in liquid ammonia afforded pyrido[1,2-a]benzimidazoles via SRN1 mediated C–N bond forming reactions in moderate to excellent yields (58–94%). This general ...
Synthesis of carbazoles by intramolecular arylation of diarylamide anions
(American Chemical Society, 2009-12)
The synthesis of a series of substituted 9H-carbazoles by the photostimulated SRN1 substitution reactionwith diarylamines as starting substrate was performed. The diarylamines were obtained by two approaches,the Pd-catalyzed ...
"Transition-metal-free" synthesis of carbazoles by photostimulated reactions of 2′-halo[1,1′-biphenyl]-2-amines
(American Chemical Society, 2014-12)
An efficient and simple protocol for the preparation of a series of 9H-carbazoles by photostimulated SRN1 substitution reactions is presented. Substituted 9H-carbazoles were synthesized in low to excellent yields (up to ...
Iterative double cyclization reaction by SRN1 mechanism: A theoretical interpretation of the regiochemical outcome of diazaheterocycles
(Royal Society of Chemistry, 2015-04-13)
In this report, we present a synthetic and mechanistic study of novel iterative double cyclization intramolecular SRN1 reactions from diamides bearing two aryl iodide moieties. This cyclization affords aromatic diazaheterocyclic ...
Intra- vs inter-molecular electron transfer processes in C[sbnd]N bond forming reactions. Photochemical, photophysical and theoretical study of 2′-halo-[1,1′-biphenyl]-2-amines
(Pergamon-Elsevier Science Ltd, 2016-12)
N-Arylation reaction is obtained when 2′-halo-[1,1′-biphenyl]-2-amines are irradiated in basic medium. On the basis of photochemical, photophysical experiments and computational studies we propose that carbazoles are formed ...
Photoinitiated Synthesis of Sulfides in Water
(Csiro Publishing, 2016-04)
Herein, we report a synthetic route to obtain aryl sulfides using inexpensive and non-toxic reactants and water as solvent,that avoids the use of catalysts or heating. The photoinduced reaction between soluble substrates ...
Synthesis of phthalonitrile derivatives by photoinduced reactions: New unsymmetrical substituted zinc phthalocyanines
(World Sci Publ Co Inc, 2015-10)
The synthesis of new phthalonitrile derivatives by photoinduced reaction is described. Novel unsymmetrically substituted Zn(II) phthalocyanine bearing an aryl alcohol group (ArZnPc) was synthesized by the ring expansion ...
