Versuchsvorschrift
Sixty five g (0.306 mole) of neat phenyl p-toluate were maintained in the temperature range of 280°-310° C. (boiling point) while a slow stream of nitrogen was bubbled in from below the surface (sparged). Sulfur (1.92 g, 0.060 mole) dissolved in more phenyl p-toluate (20 g, 0.099 mole) at 100° C. was added slowly with stirring over a period of 2-3 hours. The heating, stirring and nitrogen sparging were continued an additional four hours and then the mixture was allowed to cool near 80° C. and 100 mL of boiling acetone was added. The suspension was transferred to a larger flask and an additional 400 mL of acetone was added. The suspension was filtered at the boil to yield 3.8 g of diphenyl 4,4'-stilbenedicarboxylate.
