Zusammenfassung:Azo Bridges from Azines, XI. – Azo‐Boranes – A New Class of Compounds Rigid systems with azo bridges of 2,3‐diazabicyclo[2.2.1]hept‐2‐ene (DBH)‐ and 2,3‐diazabicyclo[2.2.2]oct‐2‐ene (DBO)‐type form azo‐boranes as stable, colourless solids on addition of BH3‐SMe2 or BH3‐THF (1–3, 5, 6, 8). On reaction of stoichiometric amounts of the two components CC double bonds are not attacked (2, 8, exception 4). So far unexplained violet and blue colorations of the reaction mixtures are described.
