Abstract A new benzimidazole based Pd(II) Schiff base complex was prepared and its catalytic activity was evaluated for Suzuki cross-coupling reactions in ethyl-methyl imidazolium hexafluorophosphate [EMIM PF6] ionic liquid at ambient temperature. The system provides a stable and reusable method for coupling reactions. Optimization for suitable reactionconditions were studied with respect to the effect
Palladium-catalyzed chemoselective and regioselective cross-coupling reactions of 2,3-dichloro-1,4-(trifluoromethanesulfonyloxy)naphthalene with aryl boronic acids selectively afforded a variety of mono-, di-, and tetraphenylnaphthalenes. These reactions proceeded with excellent chemoselectivity in favor of the triflate functional group at the C-1 and C-4 positions of naphthalene.
