Abstract:
1. A method for selecting at least one catalyst from a library of catalysts for its reactivity with regard to a chemical conversion, comprising: a) testing the catalytic activity of a first catalyst belonging to said library of catalysts with regard to a reaction medium comprising, as compound to be converted, at least one reactivity probe having a specific or nonspecific labeling system and comprising at least one reaction unit capable of reacting according to said chemical conversion, said labeling system being a compound of general formula (I): with: Ar representing a condensed or noncondensed aryl group which can comprise one or more heteroatoms chosen from nitrogen, oxygen and sulfur, it being possible for said group to be substituted by one or more halogen atoms, C X representing a C n representing 1 or 0, P representing a labile unit, which provides for the bonding of said label of general formula (I) to the reactivity probe, and □ representing the point of anchoring of the label to the reactivity probe, b) analyzing, on conclusion of said catalytic test, said reaction medium so as to qualitatively and/or quantitatively characterize the compounds formed, c) repeating stages a) and b) for at least one other catalyst of said library, d) comparing the analytical results obtained for each catalyst so as to characterize at least one catalyst having the required reactivity with regard to said chemical conversion.
