Participants

Reaction Steps

Under an atmosphere of argon, 9-(4-chlorophenyl)-10-(4-(2,2-diphenylvinyl)phenyl)anthracene (2.4 g, 4.4 mmole), diphenylamine (0.9 g, 5.3 mmole, 1.2 eq), tris(dibenzylideneacetone)dipalladium(0) (0.1 g, 0.11 mmole, 5% Pd), a toluene solution of tri-t-butylphosphine (66% by weight, 0.05 ml, 0.16 mmole, 0.7 eq to Pd) and sodium t-butoxide (0.6 g, 6.3 mmole, 1.4 eq) were suspended in anhydrous toluene (20 ml). The resultant suspension was refluxed for 8 hours. The reaction mixture was filtered and washed with toluene, water and methanol, and a green solid substance was obtained. The obtained solid substance was suspended in boiling toluene (40 ml). After the suspension was cooled while being left standing, the suspension was filtered, and a green solid substance (2.4 g, 81%) was obtained. The result of examination of the obtained product in accordance with 1H-NMR was as follows:
