  • Publication number: 20080175781
    Abstract: Metal hydride materials react with BZ3 compounds in the presence of ligand to form BH3-L compounds. A compound of the formula HBZ2 is prepared from a compound of the formula BZ3 by reacting a first amount of a compound of the formula HBZ2 with a metal hydride material “MH” and a compound “L” to form a material of the formula BH3-L, and then reacting the BH3-L thus formed with a compound of the formula BZ3 to form HBZ2 in a second amount greater than the first amount of HBZ2. Z is selected from alkoxy, aryloxy, amido, arylamido, doubly substituted alkoxy, doubly substituted aryloxy, doubly substituted amido, doubly substituted arylamido, alkoxy-amido, and aryloxy-arylamido. When Z is bidentate, then HBZ2 has a ring structure. “L” is selected from ethers, aromatic ethers, amines, aromatic amines, heterocyclic nitrogen compounds, sulfides, aromatic sulfides, and heterocyclic sulfur compounds. “L” becomes a ligand in the BH3-L material.

  • Patent number: 7179940
    Abstract: The invention concerns (aryl)(amino)borane compounds and a method for preparing same. Said compounds are of formula A-BH—NR1R2, wherein: R1 and R2 are selected among linear, branched or cyclic alkyl radicals, and arylalkyl radicals, or R1 and R2 form together an alkylene; and A represents an aromatic or heteroaromatic group optionally polycondensed, or a group selected among the vinyl, dienyl, polyenyl and alkynyl groups, all said groups optionally bearing at least one substituent. The compounds are obtained by a method which consists in preparing an amine-borane R1R2NH.BH3 complex, in transforming it into aminoborane R1R2NBH2 by heating, then in reacting it with an A-X compound wherein X is a leaving group.
