Versuchsvorschrift

The 1,3,6,8-tetrabromopyrene is obtained in an amount of 564 parts and a purity of about 83%, which corresponds to a yield of about 2% of theory, based on 100% pure pyrene, which on further processing to naphthalene-1,4,5,8-tetracarboxylic acid gives 258 parts of naphthalene-1,4,5,8-tetracarboxylic 1,4-monoanhydride.
