a novel mode of access to polyfunctional organotin compounds and their reactivity in Stille Cross Coupling reaction
Journal of Organometallic Chemistry, 2009Co-Authors: Sandrine Lamandelangle, Jerome Thibonnet, Mohamed Abarbri, Alain DucheneAbstract:Mono-, di-, tri- and tetra-functional organotin compounds were easily prepared in a sonicated Barbier reaction using ultrasound technology via Coupling reaction of organo halides with tin halides (Bu3SnCl, Bu2SnCl2, BuSnCl3, SnCl4) mediated by magnesium metal. The di- and tri-functional organotin compounds were tested in a Stille Cross-Coupling reaction in order to ascertain how many groups were transferred.

solvent free hydrostannation and Stille reactions using ionic liquid supported organotin reagents
Tetrahedron, 2013Co-Authors: Djibril Faye, Fabien Boeda, Mykhailo Vybornyi, Stephanie LegoupyAbstract:Hydrostannation reactions were performed cleanly using ionic liquid supported organotin reagents. These green reducing agents were used both under free radical and palladium-catalyzed conditions. One of the new ionic liquid supported organotin reagents so obtained was evaluated successfully in Stille Cross-Coupling reactions to give aryl-substituted allylic alcohols in solvent free conditions.

European Journal of Organic Chemistry, 2011Co-Authors: Nicolas Louaisil, Phuoc Dien Pham, Fabien Boeda, Djibril Faye, Annesophie Castanet, Stephanie LegoupyAbstract:Efficiency of ionic liquid supported organotin reagents in Stille Cross-Coupling reactions involving aryl bromides has been investigated. In a general manner, products were isolated with good yields by using a very simple catalytic system without the need of solvent, ligand, or additives. The organotin compounds were recycled without loss of activity and the contamination by tin was limited and controlled ([Sn] < 3 ppm).

Stille Cross Coupling reactions with tin reagents supported on ionic liquids
ChemInform, 2009Co-Authors: Phuoc Dien Pham, Juergen Vitz, Cecile Chamignon, Arnaud Martel, Stephanie LegoupyAbstract:New ionic-liquid-supported tin reagents were synthesized and used in Stille Cross-Coupling reactions. High yields of biaryls were obtained under low-temperature, solvent-free, ligand-free conditions, with simple purification techniques. Moreover, the tin compound could be recycled up to five times without significant loss of reactivity. An expanded catalytic cycle for the Stille Cross Coupling reaction is proposed in order to explain side products that were formed under certain reaction conditions.(© Wiley-VCH Verlag GmbH & Co.

cyclocarbopalladation 5 exo dig cyclization versus direct Stille Cross Coupling reaction the influence of the α β propargylic substitution
Organic Letters, 2003Co-Authors: Bahaa Salem, Estelle Delort, Philippe Klotz, Jean SuffertAbstract:Several bicyclic compounds bearing a 1,2-cyclopentanediol have been prepared from various anti- or syn-γ-bromopropargylic diols and cis-dioxolanes under palladium(0) catalysis.
