The use of a functionalized organosilicon compound as a coupling agent between an inorganic filler and an elastomer in an elastomer composition including an isoprene elastomer and a reinforcing inorganic filler is disclosed. The compound is selected among functionalized organosilicon compounds including at least one double bond C═C or C═N, and not including any C═C—C═O bonds or N═N bonds, and reacting with the isoprene units according to an electrocyclic reaction, in particular according to a standard cycloaddition reaction [2+1], [2+2], [3+2] or a Diels-Alder reaction [4+2] or an ene-synthesis reaction other than an ene-synthesis reaction between an isoprene unit and a C═C—C═O or N═N function. Also described, are elastomer composition(s) obtained and items manufactured using such compositions.
