Borazines borazanes

Condensation processes are used to prepare oligomers of organosiloxanes, silazanes, silthianes, borazines, borazanes, metaborates, metaphosphates, phosphazenes, thiazyls, alazanes, metal oxides and so on. 

The complexes were obtained after the removal of thf and SMe2 under vacuum. Thermolysis of these complexes at 120 °C led to borazanes as intermediates. A further thermolysis at 200 °C gave the desired borazines, which were purified by distillation.
