  • Publication number: 20210340331
    Abstract: A process for preparing a polyaminoborane comprising reacting at least one monomer with an aminoborane, wherein the at least one monomer is selected from the group consisting of ammonia, a primary amine and a substituted or unsubstituted hydrazine; and wherein the aminoborane comprises a borane substituted by a secondary amino group; polyaminoboranes obtainable by said process; use of said polyaminoboranes for the preparation of a ceramic precursor or a ceramic, the production of boron nitride, or the storage and/or production of dihydrogen; ceramic precursors, ceramics, hydrogen cells or energy materials comprising said polyaminoboranes.

  • Patent number: 8106089
    Abstract: The invention relates to a compound represented by general formula (I) wherein Z represents N, O or S, and A represents a CH group, a nitrogen atom or an NL+ group wherein L represents a straight-chained or branched C1-C12 alkyl group. The invention also relates to a method for the preparation thereof and the use thereof as an antimitotic.

  • 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.
