    Description / Table of Contents: Preparation of Chloropentacyanobenzene1, 3, 5-Trichloro-2,4,6-tricyanobenzene (2a) reacts with the sodium salts of β-ketoesters by exchange of two chlorine atoms to give the compounds 6a-c. Of these 6c, by partial saponification and decarboxylation, yields diethyl 6-chloro-1,3,5-tricyanobenzene-2,4-diacetate (9), which reacts with ethyl nitrite in dimethylformamide to give the dioxime 10. By Beckmann fragmentation of 10 with phosphorus pentachloride chloropentacyanobenzene (5) is obtained.
    Notes: 1. 3. 5-Trichlor-2.4.6-tricyan-benzol (2a) reagiert mit den Natriumsalzen von β-Ketoestern unter Austausch von zwei Chloratomen, wobei die Verbindungen 6a-c entstehen. Von diesen ergibt, 6c durch partielle Verseifung und Decarboxylierung 6-Chlor-1.3.5-tricyan-benzoldiessigsäure-(2.4)-diäthylester (9), der mit Äthylnitrit in Dimethylformamid zum Dioxim 10 reagiert. Aus 10 wird mit Phosphorpentachlorid durch Beckmann-Fragmentierung das Chlorpentacyanbenzol (5) erhalten.
