Abstract
A boron trihalide-trialkylamine compound is formed as a secondary product in the preparation of diborane by reacting a borazane of general formula BH3 NR3, where R is an alkyl, alkaryl, or aryl radical, with a boron halide, boron halide etherate, or aluminium trichloride. In one form of the process an aluminium trialkyl is prepared from aluminium, hydrogen, and an olefine; this trialkyl is reacted with boron fluoride or a compound of boron fluoride and a tertiary amine to form a boron trialkyl, and this trialkyl together with a tertiary amine is heated with hydrogen under pressure to yield a by-product paraffin and a trialkyl borazane, which is in turn reacted with boron fluoride to form diborane and a boron fluoride-trialkylamine compound, which latter may be recovered and employed in the preparation of further boron trialkyl. Specification 770,707 is referred to.ALSO:Diborane is produced by reacting a borazane of general formula BH3NR3 with a boron halide or halide etherate, or aluminium trichloride. R may be alkyl, aralkyl or aryl; triethyl, dimethyl cyclohexyl, and dimethyl phenyl borazanes are specified. The reaction may be effected at a slight negative pressure and in the presence of a solvent which may be an ether, hydrocarbon or tertiary amine, specifically, ether and xylene. Boron fluorides or chlorides or boron fluoride etherates or thioetherates may be employed. In a preferred procedure, the trialkyl borazane reactant is prepared by treating a boron trialkyl with hydrogen under pressure in the presence of a tertiary amine. The borazane so produced on treatment with boron trifluoride gives the diborane product and a boron trifluoride trialkylamine compound. The latter may be reacted with aluminium trialkyl to form boron trialkyl and aluminium fluoride. Specification 770,707 is referred to.
