CCLXXXII.—Synthesis of anthracene homologues. Part I. 2 : 6- and 2 : 7-Dimethylanthracenes

Cross-Linking and Modification of Poly(ethylene terephthalate-co-2,6-anthracenedicarboxylate) by Diels−Alder Reactions with Maleimides

“…24 2,5,4′-Trimethylbenzophenone, 1. 25 The title compound was prepared by Friedel-Crafts acylation of p-xylene (69 g, 0.65 mol) with p-toluoyl chloride (100 g, 646 mmol) in CS2 (150 mL) in the presence of AlCl3 (100 g, 750 mmol). Workup and purification by distillation under vacuum (110-120 °C, 0.05 mmHg, lit.…”

“…Workup and purification by distillation under vacuum (110-120 °C, 0.05 mmHg, lit. bp 25 2,6-Anthraquinonedicarboxylic Acid, 4. 2,5,4′-Trimethylbenzophenone, 1 (30 g, 0.13 mol), was heated at reflux (∼360 °C) under air for 6 h and cooled.…”
