Synthesis of 2,2'-Biimidazolium-Based Ionic Liquids: Use as a New Reaction Meand Ligand for Palladium-Catalyzed Suzuki Cross-Coupling Reactions. —
37- 121 dium
A number of new title compounds such as (VI)—(IX) is prepared. Most of the monoquaternary derivatives are room-temperature ionic liquids. (IXb) is found to be an excellent solvent and ligand for Suzuki cross-couplings. It can be recycled 14 times without significant loss of catalytic activity. — (XIAO, J.-C.; SHREEVE*, J. M.; J. Org.
