Yield:98-51-1 90 %Chromat.

Reaction Conditions:

with triethylsilane in ethanol at 20; for 0.166667 h;Inert atmosphere;

Steps:

2.4. General procedure for benzyl alcohol hydrogenolysis
General procedure: To a solution of benzyl alcohol (1mmol) and triethylsilane (amountindicated in Table 2) in ethanol (5mL)was added 10 mg of Pd NPs/rGO under an argon atmosphere. The resulting mixture was stirred for thetime indicated in Table 2 prior to GC-MS analysis. The resultingmixturewas filtered and washed by ethyl acetate for catalyst separation. Thepure product in entry 1 was isolated by distillation; for entries 2-10the products were isolated by column chromatography using hexane/ethyl acetate (9/1) as eluent.
