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

摘要

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.
