## Abstract Das aus 2.7‐Dimethyl‐octadien‐(2.6)‐diol‐(1.8) gebildete 1.8‐Dibrom‐2.7‐dimethyl‐octadien‐(2.6) wird mit 2 Moll. Na‐Malonsäurediäthylester zum 1.1.10.10‐Tetracarbäthoxy‐3.8‐dimethyl‐decadien‐(3.7) umgesetzt; Verseifung und Decarboxylierung führt zur 4.9‐Dimethyl‐dodecadien‐(4.8)‐disäure
In the molecule of the title compound, C 17 H 16 Br 2 N 2 , the 4,10bromo-2,8-dimethyl analogue of Tro ¨ger's base, the two aryl rings are offset with respect to one another by virtue of the diazocine bridge. There are two crystallographically independent molecules in the unit cell and both of these
