Procedure

A mixture of 1.04 g of 1-bromo-4-cyclopent-1-enyl-benzene (4.7 mmol) and 100 mg of PtO2 in 25 ml toluene was stirred under an atmosphere of hydrogen at RT for 6 h. The reaction mixture was then filtered and the filtrate was evaporated to dryness to give 1.0 g of 1-bromo-4-cyclopentyl-benzene (95%) as a yellow liquid.

Workup
