Catechol → 1,2-Bis(benzyloxy)benzene

Participants

Reaction Steps

A mixture of catechol (11.0 g, 0.10M), benzylbromide (25.0 ml, 0.21M) and finely powdered anhydrous K2CO3 (44.2 g, 0.32M) in DMF (60 ml) was stirred at room temperature under N2 for 72 hours. The mixture was then diluted with Et2O and filtered. The ether solution was washed with three portions of distilled water, one portion of saturated NaCl solution, dried (K2CO3) and concentrated in vacuo. The residue was recrystallized from hexane to give dibenzyloxybenzene (27.04 g, 93% yield) as white crystal, mp 58°-59° C. (literature: Page et al., J. Org. Chem. 27, 218 (1962), mp 58°-59° C.).
