Procedure

In a 100-milliliter three-necked flask equipped with a stirring device and a nitrogen substituting device, 1.2 g of a Pd-C catalyst (a 5% product, containing 55.9% of water) and a solution of 12.4 g of 1,1-diphenyl-1-heptene in 50 milliliters of tetrahydrofuran were introduced, and contacted with hydrogen gas at a normal pressure with stirring. After hydrogen absorption was stopped, the catalyst was filtered off and the solution was concentrated. Thereafter, by carrying out a distillation under a decreased pressure, 9.8 g of 1,1-diphenyl heptane was obtained as colorless liquid.
