实验过程

Then, 5% Pd—C 4 g and ethanol 100 ml were added to 3-(5-fluoro-1-pentenyl) fluorobenzene 86 g (472 mmol) to conduct a reaction of catalytic hydrogenation reduction. After the hydrogen absorption was stopped, the catalyst was filtered off, and the filtrate was distilled(62° C./2 mmHg) to obtain 3-(5-fluoropentyl) fluorobenzene 56 g. (Yield: 64.4%).
