Beschreibung

Borazole (borazine) is a colourless liquid with an aromatic smell. With water, it decomposes to form boric acid, ammonia, and hydrogen. The reaction product of boron and ammonia at high temperatures is also known as inorganic benzene.

Chemische Eigenschaften

inorganic analog of benzene; colorless liquid; preparation: heating equimolar mixture of ammonia and BH3 at 250°C–300°C for 30min [MER06] [HAW93]

Application

Films that were deposited thermally from borazine vapor were found to be too reactive to be suitable for fabricating masks for X-ray lithography. However, films containing predominately cubic boron nitride, CBN [10043-11-5], were deposited using ions extracted from a borazine plasma via an ion beam. Very hard, adherent films were deposited on ceramic, glass, stainless steel, etc. An obvious practical application is the hardening of tool surfaces to markedly extend their life. A thermally deposited film of hexagonal BN [10043-11-5], from B3N3Cl6 [19087-72-0] at 900 ℃, protected SiO2 tubes from halide corrosion. A copolymer between 2,4,6-tributylborazine [7325-06-6] and an unsaturated N,N'-hexamethylenebiscarboxamide was useful for hardening epoxy resins. Trichloroborazine was used as part of a catalyst mix for the polymerization of propene. Flexible BN coatings on copper or copperbase alloys were formed from gaseous 2,4,6- trichloroborazine. The films were stable to 700℃ in air.

synthetische

Borazine was discovered when a mixture consisting of B3H6 and NH3 (or the addition product B3H6-NH3) was heated in a sealed tube. It can also be produced by pyrolysis of a mixture of LiBH4 and NH4Cl. The best yield is obtained by reducing (ClBNH)3  with LiBH4 in n-butyl ether. This reaction also yields B2H6.

Allgemeine Beschreibung

Borazine can be prepared by copyrolysis of NaBH4 and NH4Cl in a highboiling glyme, by reduction of trichloroborazine, or by pyrolysis of ammonia borane in diglyme.
A large body of literature exists on the preparation and chemistry of symmetrically and unsymmetrically substituted borazines. B-Substituted trihaloborazines, readily prepared from BX3 and NH4Cl, react with Grignard reagents to give symmetrical trialkyl- or triarylborazines. Symmetrically substituted N-trialkylor N-triarylborazines are readily prepared from LiBH4 and RNH3Cl, or by pyrolysis of RNH2BH3.
Borazine is thermally stable at 0 C, but decomposes slowly at ambient temperature. Borazine hydrolyzes slowly, but trihaloborazines hydrolyze quite rapidly. Hydrogen halides form 1 : 3 adducts with borazine, which decompose to trihaloborazines on warming.
