  • (Aryl)(amino) borane compounds, method for preparing same
    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.
