摘要:
The invention relates to a drop microreactor, i.e. a microreactor comprised of a drop of a particular liquid, whereby this microreactor does not walls, and the interface of the particular liquid with the ambient medium and with the support onto which the drop is deposited define the boundaries of the microreactor. The microreactor is characterized in that it is comprised of a drop containing at least one ionic liquid. The invention also relates to methods for carrying out chemical or biochemical reactions and/or a mixture of the two while using said microreactor as well as to a lab-on-chip comprising a microreactor of the aforementioned type.

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 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.
摘要:
The present invention relates to a new process for the preparation of an arylborane compound, by arylation of a B-H bond, which comprises a step (1) of contacting an arenediazonium salt or a heteroarenediazonium salt with an organoboron compound containing at least one B-H bond, in a reaction medium containing a solvent, in the absence of base, in the absence or in the presence of an activating agent, for the preparation of an arylborane compound, and a possible step (2) of recovery and purification of said arylborane compound obtained at the step (1), said arylborane being in particular an aminoarylborane, and a possible step (3) of refunctionalisation of said arylborane obtained at step (1) or (2) for the preparation of aryl boronic derivatives or arylborates.
