反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: In a 200-milliliter three-necked flask equipped with a stirring device, a thermometer and a nitrogen substituting device, 17.4 g of iron chloride, 16.7 g of paranitrobenzoyl chloride and 40 milliliters of 1,2-dichloroethane were introduced. Then, a solution of 9.0 g of 1,1-diphenyl heptane in 10 milliliters of 1,2-dichloroethane was added dropwise for 15 minutes with an ice bath. Thereafter, the solution was stirred for 3 hours and 40 minutes with heating to a reflux temperature. After the end of the reaction was confirmed by a liquid chromatography, the solution was poured in ice water containing dilute hydrochloric acid, and then extracted with chloroform. The solution was washed with hydrochloric acid, an aqueous solution of sodium hydroxide and water, and then dried with anhydrous sodium sulfate. After removing off the solvent by a rotary evaporator, the solution was dissolved in chloroform and subjected to a separating operation by a column chromatography with silica gel, to obtain 14.4 g of 1,1-bis(4-(4-nitrobenzoyl)phenyl)heptane as red oil. In a 200-milliliter three-necked flask equipped with a stirring device with heating to a reflux temperature extracted with chloroform The solution was washed with hydrochloric acid an aqueous solution of sodium hydroxide and water, and then dried with anhydrous sodium sulfate After removing off the solvent by a rotary evaporator the solution was dissolved in chloroform

实验步骤: 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. In a 100-milliliter three-necked flask equipped with a stirring device were introduced After hydrogen absorption the catalyst was filtered off the solution was concentrated a distillation under a decreased pressure
