Procedure

Pd/C (5 mol %) is weighed into a reaction flask. A solvent mixture consisting of ethanol and water (4:1) and ammonium formate (30 mol %) is added, the reaction flask is capped with a rubber septa and the mixture is heated (80° C.) for 2 minutes. Formic acid (3 equivalents) and then benzyl alcohol are added by syringe. The reaction is run for 20 minutes and the reaction is quenched with brine. The product is extracted by DCM and the organic phase is dried by Na2SO4. The product ethylbenzene was analyzed by 1H NMR and produced in 20% yield.
