A composition comprises (A) an unsaturated compound including at least one aliphatically unsaturated group per molecule, subject to at least one of the following two provisos: (1) the unsaturated compound (A) also includes at least one silicon-bonded hydrogen atom per molecule; and/or (2) the composition further comprises (B) a silicon hydride compound including at least one silicon-bonded hydrogen atom per molecule. The composition further comprises a catalyst (C). The catalyst (C) has the formula X2Pt(II)Y2, where each X is the same and is selected from a fluorinated acetate group or a halide, and each Y is independently selected from a substituted or unsubstituted pyridine group, with the proviso that each Y is not linked to the other Y when substituted. L'invention concerne une composition comprenant (A) un composé insaturé comprenant au moins un groupe aliphatique insaturé par molécule, soumis à au moins l'une des deux conditions suivantes : (1) le composé insaturé (A) comprend également au moins un atome d'hydrogène lié au silicium par molécule ; et/ou (2) la composition comprend en outre (B) un composé hydrure de silicium comprenant au moins un atome d'hydrogène lié au silicium par molécule. La composition comprend en outre un catalyseur (C). Le catalyseur (C) a la formule X2Pt(II)Y2, où chaque X est identique et est choisi parmi un groupe acétate fluoré ou un halogénure, et chaque Y est indépendamment choisi parmi un groupe pyridine substitué ou non substitué, à condition que chaque Y n'est pas lié à l'autre Y lorsqu'il est substitué.
