摘要:
The invention relates to the use of a onium salt functionalized by at least one organic function, as a soluble support, in the presence of at least one organic solvent, for organic synthesis of a molecule, in a homogenous phase, by at least one transformation of said organic function. The onium salt enables the synthesized molecule to be released. The onium salt is present in liquid or solid form at room temperature and corresponds to formula Al+, X1-, wherein A1+ represents a cation and X1- représents an anion.

The invention relates to the use of an ionic liquid as a matrix liquid for organic synthesis in a homogeneous phase on a soluble medium, said ionic liquid being present in the form of a liquid or solid at room temperature, having formula A1+X1-, A1+ representing a functional or non-functional cation or a mixture of cations wherein none of said cations are functional or at least one of the cations is functional, and X1- a functional or non-functional anion or a mixture of anions wherein none of the anions are functional or at least one of the anions is functional.

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 arlyalkyl 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.
