Reaction Conditions:
with bromine in chloroform; for 4 h;Inert atmosphere;Reflux;
Steps:
Intermediate 1: Synthesis of 1,6- and 1,8-dibromopyrene
58 g (0.287 mol) of pyrene are initially introduced in 1750 ml of chloroform. A solution of 31 ml (0.609 mol) of Br2 in 250 ml of chloroform is subsequently added dropwise at RT with exclusion of light. The reaction mixture is heated under reflux for 4 h. After cooling, the precipitated solid is filtered off with suction and washed with ethanol and dried. The solid obtained is recrystallised 3 times from CHCI3. Yield: 1 ,6- dibromopyrene 73.4 g (0.201 mol), 71.1% of theory, and 1 ,8-dibromopyrene 20.6 g (0.06 mol), 20% of theory.
