Processing of borazine oligomers

By heating the monomer at 70 C in a pressure reactor vessel, self-condensation occurs and hydrogen is evolved. This reaction proceeds in a very easy, controlled manner without the need for additional catalysis. 

Mass spectrometry can also be used in order to gain insight into the mechanism of borazine polymerization. Of particular interest is the means by which polynuclear species such as the naphthalene analog are formed. Examination of the gaseous products reveals that hydrogen is the primary byproduct of the reaction with a small amount of ammonia. 

The mass spectrum of borazine, B N3H, shows that it has a propensity to decompose into several stable fragments, including 3 2 3 (Figurc 2.9). Presumably the ring fragments
