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.

Polyaminoboranes

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 NLgroup wherein L represents a straight-chained or branched C-Calkyl group. The invention also relates to a method for the preparation thereof and the use thereof as an antimitotic.

Anti-tubulin acting arylpyrrol, arylfuran and arylthiophene derivatives, method for the preparation thereof and for the use thereof as an antimitotic

The invention concerns (aryl)(amino)borane compounds and a method for preparing same. Said compounds are of formula A-BH&#x2014;NRR, wherein: Rand Rare selected among linear, branched or cyclic alkyl radicals, and arylalkyl radicals, or Rand Rform 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 RRNH.BHcomplex, in transforming it into aminoborane RRNBHby heating, then in reacting it with an A-X compound wherein X is a leaving group.
