Yield:1563-38-8 76.2%

Reaction Conditions:

in toluene at 144.84; for 4 h;Autoclave;Reagent/catalyst;Temperature;Time;

Steps:

Synthesis of benzofuranol
3.0 mmol of pyrocatechol, calculated amounts of3-chloro-2-methylpropene and ILs were added to a 100 mL Parr reactor with 23 mL of toluene. The reaction mixture was heated to 418 K and held constant for the desired time. The resultant mixture formed two layers after cooling to ambient temperature, and theupper phase was separated and analysed using a capillary GC (SGE BPX5: 30 m × 0.25 mm × 0.25 m)equipped with a flame ionisation detector and o-xyleneas an internal standard. The toluene in the separated upper phase was removed by distillation and the yieldof benzofuranol was obtained.
