• An efficient phosphine-free palladium coupling for the synthesis of new 2-arylbenzo[b]thiophenes

  Straightforward and rapid access to 2-arylbenzo[b]thiophenes has been developed. It involved a catalytic coupling of 3-activated benzo[b]thiophenes with several aryl halides in the presence of a phosphine-free palladium system. In case of fragile functional groups such as aldehydes, a quaternary ammonium was used as an additive as with the other substrates, the coupling performed better and faster in the presence of a crown ether, the best one being DCH-18-C-6, with good yields and low reaction times. This method would provide a direct access to novel structures of biological interest. (C) 2004 Elsevier Ltd. All rights reserved.
• Cobalt-Catalyzed C–H Cyanation of (Hetero)arenes and 6-Arylpurines with <i>N</i>-Cyanosuccinimide as a New Cyanating Agent

  A cobalt-catalyzed C–H cyanation reaction of arenes has been developed using N-cyanosuccinimide as a new electrophilic cyanating agent. The reaction proceeds with high selectivity to afford monocyanated products with excellent functional group tolerance. Substrate scope was found to be broad enough to include a wide range of heterocycles including 6-arylpurines.
