A method (P) for hydrosilylating at least one compound (C), including at least one unsaturation in the presence of an organosilicon compound (O) including at least one hydrogen atom per molecule bonded directly to a silicon atom, and of a catalytic hydrosilylation system including a structured porous material (A) including pores and an inorganic structure consisting of silicon oxide walls, in which metal nanoparticles are contained.


A photoinitiator composition is described that includes a specific iodonium salt combined with a hydrogen donor that is a Guerbet alcohol that can also act as a solvent. This initiator system can solve problems concerning odor, in particular after the polymerization/cross-linking of conventional iodonium salts.
