Diphenylamine → HCID 23067343, compound

Participants

Reaction Steps

Under an atmosphere of argon, 9-(4-chlorophenyl)-10-(3,4-diphenylphenyl)anthracene (2.3 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 mixture was refluxed for 8 hours. The reaction mixture was filtered and washed with toluene, water and methanol, and a light yellow 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 light yellow solid substance (2.2 g, the yield: 78%) was obtained. It was confirmed in accordance with 1H-NMR and FDMS that the obtained product was Compound (A11).
