    摘要: The invention relates to a process for the preparation of pyrene compounds of the formula ##STR1## by reaction of cyanuric chloride with pyrene in the presence of an aluminum halide in an aromatic solvent in a Friedel-Crafts reaction, which comprises using as solvent non-polar, halogen-free aromatic compounds, preferably composed of methyl-, ethyl- and/or propyl-substituted benzene, and carrying out the reaction in the presence of non-aqueous bases, particularly carbonates of alkaline earth and alkali metals, bicarbonates of alkaline earth and alkali metals, and also alkali metal alcoholates of the formula MOR (R=C.sub.1 -C.sub.4 -alkyl, M=alkali metal).
