Reaction information

*#Reaction file

*Reaction file type CDX
*Procedure Repeating the procedure described by Loupy, in a sealed Schlenk tube hydroquinone (0.55 g, 4.99 mmol), Tetrabutylammonium bromide, TBAB (63 mg, 9% w/w KOH) and KOH powder (0.7 g, 12.47 mmol, 2.50 eq.) were stirred for 10 minutes before adding octylbromide (2.16 mL, 2.42 g, 12.53 mmol, 2.51 eq.) and heating to 80 ºC for 17 h. The reaction mixture was then dissolved in Et2O and washed with water, the organic phase was dried over anhydrous MgSO4and the solvent evaporated to afford the crude title compound (1.87 g). The pure product (1.03 g, 3.08 mmol) was obtained by column chromatography on silica gel, using as eluent (5/1) hexane/DCM (Rf0.15); this was then recrystallized from EtOH as white thin flakes (0.77 mg, 2.30 mmol, yield 46%).
*Yield (%) 46 %
*Type of Yield Isolated pure product
