Abstract:

Borazine is the foremost example of an inorganic compound that can be closely compared to an organic species, i.e., benzene. Hence, studies on this six-membered B3N3 heterocyclic system have been popular and literally hundreds of borazine derivatives are known. However, most of them are symmetrically substituted species of the type RBNR. Relatively few unsymmetrically substituted derivatives have been described and their chemistry has been investigated only sparingly. Within the context of preparative studies on discrete polycyclic boron-nitrogen systems as potential precursors for macromolecular materials, the synthesis of the trisborazin-2-yl amine framework seemed to be an interesting point of origin. Detailed studies such species require convenient access to unsymmetrically B-substituted borazines of the types XR2B3N3R3 and X2RB3N3R3 and where X is a reactive site in highly purity. The present report describes the preparation and characterization of various such unsymmetrically B-substituted borazines as well as attempts to synthesize the trisborazin-2-ylamine skeleton.
