Reaktionsschritte
0.224 g (1 millimol) of palladium acetate, 12.65 g (50 millimols) of naphthalene-2,6-dicarboxylic acid dichloride, 13.04 g (125 millimols) of styrene and 18.53 g (100 millimols) of tri-n-butylamine in 50 ml of p-xylene are stirred for 2 hours at 120° C. The crude product is extracted in a Soxhlet and recrystallised from tetrahydrofuran. 6.1 g (37% of theory) of 2,6-distyrylnaphthalene are obtained as pale yellow crystals of melting point 294.7° C.
