Abstract: Disclosed is the application of alkoxyamine-borane complexes for the storage of hydrogen.

Abstract: A new process for the preparation of an arylborane compound, by arylation of a B—H bond, which includes 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 the arylborane compound obtained at the step (1), the arylborane being in particular an aminoarylborane, and a possible step (3) of refunctionalization of the arylborane obtained at step (1) or (2) for the preparation of aryl boronic derivatives or arylborates.
