Borazine, Chemistry

Assignment Help:

Reaction of ammonia with diborane at 475K gives a compound B3N3H6 known as borazine or borazole:

Borazine is best prepared by reducing B-trichloroborazme with sodium borohydride,  NaBH4. B-trichloroborazine is first prepared by heating BCl3 with NH4CI.

Borazine has many physical properties closely similar to those of isoelectronlc benzene as shown in Table 6.4. Therefore, sometimes it is also called as inorganic benzene.

Borazine, however, is more reactive than benzene. It readily reacts with H20, MeOH and HX to yield 1:3 adducts which eliminate Hz on being heated to 373 K, e. g :

B3N3 H6+3H2O--------------- >[BH(OH)NH2] 3---------------->[B(OH)NH]3+3H2

B3N3H6+3HCL-------------- >[BH (Cl) NH2]3------------------>B3N3HECL3+3H2
