実験手順

5 grams of 9,10-dibromo anthracene and 0.13 gram of NiCl2(dppp) were mixed with 50 ml tetraphdrofurane in a 250 ml reaction bottle, heated for reaction under 60° C. for 1 hour. Then added slowly with solution of a), stirred for reaction for 8 hours. The solvents were removed via a rotary evaporator. The residue was washed with 100 ml methanol three times and filtered. After recrytallization from toluene and methanol, 3.8 gram light yellow colored 9,10-di-(3-methylphenyl)anthracene was collected. Yield 71%. The structural formula is as follows.
