Abstract
The invention concerns (aryl)(amino)borane compounds and a method for preparing same. Said compounds are of formula A-BH—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.
