Donor-stabilized phosphenium adducts as new efficient and immobilizing ligands in palladium-catalyzed alkynylation and platinum-catalyzed hydrogenation in ionic liquids

The straightforward synthesis of a new donor-stabilized phosphenium ligand 3d by addition of bromodifurylphosphine to 1,3-dimethylimidazolium-2-carboxylate 1 is described. The obtained ligand exhibits a very strong π-acceptor character, comparable to that

Straightforward synthesis of donor-stabilised phosphenium adducts from imidazolium-2-carboxylate and their electronic properties

Cationic imidazolium-2-phosphanes were obtained by the addition of a chlorophosphane (R2PCl, R = Ph, iPr or Cy) to 1,3- dimethylimidazolium-2-carboxylate without the need for a purification step. An additional anion exchange reaction with KPFs

THE CHELETROPIC FRAGMENTATION OF HYPERVALENT THREE-MEMBERED THIAHETEROCYCLIC INTERMEDIATES

Lithio-imidazolium salts 10, generated in-situ from N'N-dimethylimidazolium salts 9, readily undergo sulfonylation with sulfur dioxide, sulfines, N-sulfinylamines, and thiirane.The resulting zwitterionic species 4 fragment thermally to yield the corresponding imidazolium thione 5 with the hypervalent three-membered thiaheterocyclic intermediates 3 connecting 4 and 5 on the reaction surface.The non-linear cheletropic fragmentation of these relatively stable hypervalent sulfuranes appears to be general for this class of compounds (3 or 4), and the experimental results are in accord with theoretical considerations.
