corresponding metal halogenides the 7-chloro-5-diazomethylbenzocycloheptatrienes 7a, b and 9a, b; isomers of type 6 are not formed. Copper(II)-acetylacetonate catalyzed thermolysis of the diazo compounds leads under ringenlargement to 8-chloro-6-phosphoryl(or carbonyl)-substituted benzocyclooctatetranes 10a-d. The X-ray structure analysis of 10a was carried out.
