Reaction Steps

1,4-bis(4-nitrophenyl)-2,3,5-triphenylbenzene was prepared according to the procedure described in L. F., "Organic Experiments", 2nd Ed., 297 (1968). 19.3 grams (0.189 moles) of phenylacetylene, 20.0 grams (0.0362 moles) of 2,5-bis(4-nitrophenyl)-3,4-diphenylcyclopentadienone, a compound of formula (II) where Ar1 and Ar2 are phenyl, and 130 mL of o-dichlorobenzene were stirred at 180° C. for 2 hours. The reaction mixture was cooled, poured into 500 mL of hexane and filtered. The reaction yielded 22.9 grams of 1,4-bis(4-nitrophenyl)-2,3,5-triphenylbenzene, a 66% yield.
