Boron nitride trichloroborazine

Amorphous boron nitride (a-BN) can be synthesized by decomposition of B-trichloroborazine and cesium [23]. Such layers are applied during production of semiconductor devices [24]. 

Highly crystalline hexagonal boron nitride layers can be formed on graphite layers which have been obtained from the CVD of benzene [128]. Low-pressure CVD originating from 2,4,6-trichloroborazine on graphite, metallic, and oxide ceramic substrates at 1050°C leads to dense, amorphous boron nitride deposits [129] see also [130]. Ceramics are frequently coated or infiltrated with a-BN by the different chemical vapor deposition (CVD) methods already...

The use of reductive (Wurtz) coupling of borazine rings by combination of B-haloborazines with Group 1 metals has also been explored. This approach has recently been reexamined by Shore who reported tiiat trichloroborazine and Cs metal react explosively at 125°C with formation of a insoluble, perhaps polymeric, solid some of which has a tubular morphology. Most significantly, the tubular structure is retained in the final boron nitride pyrolysis product...
