Abstract

Diborane, or partially halogenated boron hydrides, are obtained by vapour phase reduction of a boron trihalide with H2 at elevated temperature in the presence of a Group IB metal in elemental form, e.g. Cu or Ag, BF3, BCl3, BBr3, or BI3, may be reacted with H2 at 250 DEG -950 DEG C. and atmos. up to 50 atms. pressure for 0.01-2.5 secs., in proportion 1-60 mole H2 per mole trihalide. H2 is bubbled through BCl3 and the resulting vapour mixture contacted with the metal which may be as little as 0.01% or a bed of granular metal. The volatile reaction products B2H5Cl, BHCl2, B2H6, and HCl are separated from H2 by condensation in a liquid N2-cooled trap at -196 DEG C. HCl is volatilised at -120 to -107 DEG C. and B2H6 is volatilised at 0 DEG C. under 2 atms., and as B2H6 is removed more BHCl2 and B2H5Cl is converted to B2H6. BCl3 may be recycled. Specification 864,253 is referred to.
