Zusammenfassung:(I) of formula is prepd. by reacting acenaphthene, (II), with a chlorinating agent, ((III), in (III):(II) mol ratio 3:1 to 6:1, in the presence of (a) S, S halides or cpds. of divalent S and (b) Friedel-Crafts catalysts. (I) is a raw material in the prepn. of dyes, pesticides and optical brighteners. Pure (I) is obtd. in high yields. e.g. reaching 96%.
