Synthesis of Symmetrical and Unsymmetrical 1,3-Diheteroarylbenzenes Through Palladium-Catalyzed Direct Arylation of Benzene-1,3-disulfonyl Dichloride and 3-Bromobenzenesulfonyl Chlorides [PDF]
, 2015 International audienceThe palladium-catalyzed synthesis of unsymmetrical 1,3-diheteroarylbenzenes was investigated. The first synthetic pathway relies on the desymmetrization of benzene-1,3-disulfonyl dichloride through two successive palladium-catalyzed

First selective direct mono-arylation of piperidines using ruthenium-catalyzed C–H activation [PDF]
, 2013 : A Ru-catalyzed mono-arylation in α-position of saturated cyclic amines is reported employing a C–H activation protocol. Substitution of the pyridine directing group with a bulky group, e.g., trifluoromethyl in the 3-position, proved to be crucial to ...

Alkoxysulfonium Salts Unlock Access to New Aryl Sulfonium Salts for Cross‐Coupling
Angewandte Chemie, EarlyView.Hard‐to‐access (hetero)aryl sulfonium salts are prepared using stable methoxysulfonium salts in combination with the magnesiation of (hetero)aryl bromides. The approach allows access to aryl sulfonium salts bearing electron‐deficient (hetero)aryl rings, or electron‐rich aryl motifs in which the sulfonium motif resides at an alternative position on the ...
