Palladium Catalyzed Heck Arylation of 2,3-Dihydrofuran—Effect of the Palladium Precursor
Heck arylation of 2,3-dihydrofuran with iodobenzene was carried out in systems consisting of different palladium precursors (Pd(2)(dba)(3), Pd(acac)(2), PdCl(2)(cod), [PdCl(allyl)](2), PdCl(2)(PhCN)(2), PdCl(2)(PPh(3))(2)) and ionic liquids (CILs) with L-prolinate or L-lactate anions. All the tested...

Sumario: | Heck arylation of 2,3-dihydrofuran with iodobenzene was carried out in systems consisting of different palladium precursors (Pd(2)(dba)(3), Pd(acac)(2), PdCl(2)(cod), [PdCl(allyl)](2), PdCl(2)(PhCN)(2), PdCl(2)(PPh(3))(2)) and ionic liquids (CILs) with L-prolinate or L-lactate anions. All the tested CILs caused remarkable increases of the conversion values and in all of the reactions 2-phenyl-2,3-dihydrofuran (3) was obtained as the main product with a yield of up to 59.2%. The highest conversions of iodobenzene were achieved for the [PdCl(allyl)](2) precursor. Formation of Pd(0) nanoparticles, representing the resting state of the catalyst, was evidenced by TEM. |
