Yield:279242-09-0 99%

Reaction Conditions:

with trimethyl-(2-hydroxyethyl)ammonium chloride;potassium carbonate in glycerol at 80; for 1 h;Sealed tube;Suzuki Coupling;

Steps:

2.6. Catalytic Suzuki coupling reaction

General procedure: Typically, a 10 mL screw-capped vial was charged with arylboronicacid (1.1 mmol), aryl halide (1 mmol), K2CO3 (2 mmol),GO/Fe3O4G2/Co (1 mg, 0.4 mol %), and DES (ChCl:glycerol,3 mL). Afterward, the vial was put at 80 C to form the correspondingcoupling products (monitored by TLC). After completing thereaction, the catalyst was collected with a magnet and the reactionmixture was quenched with water and extracted with ethyl acetate(3 5 mL). The organic layer was dried with MgSO4 and evaporatedunder vacuum to yield the crude product, which was thenpurified by column chromatography using silica gel. Finally, theproducts were subjected to structural identification by 1H and13C NMR spectroscopies.
