الإجراء التجريبي

4.4 equivalents of 3-chlorophenylboronic acid, 10 equivalents of sodium carbonate in a 2 mol/L aqueous solution, and 0.12 equivalents of tetrakis(triphenylphosphine)palladium (0) were added to one equivalent of 1,3,6,8-tetrabromopyrene obtained in the same way as for EXAMPLE 1, and the mixture was subjected to heating under refluxing to allow reaction for three hours, using benzene as a solvent. 1,3,6,8-tetra(3-chlorophenyl)pyrene was obtained after deposition and purification through recrystallization of the product.
