실험 절차

In a Parr reactor, tetrakis(4-nitrophenyl)methane (17.0 grams, 34.0 mmol; prepared as described in Example B) and palladium, 10 weight percent on activated carbon (2.1-5 grams, 2.00 mmol; obtained from Aldrich Chemical Co., Milwaukee, Wis.) were added to tetrahydrofuran (450 milliliters). The reactor was closed, and the mixture was stirred under 200 pounds per square inch (13.6 atmospheres) of hydrogen pressure for 72 hours at room temperature. The mixture was then filtered through CELITE, solvent was removed from the filtrate by evaporation under reduced pressure, and the resulting white solid was triturated in chloroform. The solid was then recovered by filtration, washed with chloroform again, and dried under reduced pressure at room temperature to give the targeted tetrakis(4-aminophenyl)methane as a white powder in a quantitative yield (12.9 grams).
