Mono- or poly-functional organosilanes compounds represent a major benefit in many fields, since they allow the making of mono- or poly-functionalized organosilicon materials, which may appear as a powder, a coating or a polymer.

They also allow the making of products which appear as functionalised particles, notably functionalised nanoparticles, for example with an active remainder, which may notably be sorted out in a controlled way under the action of one or several parameters.

Many silylated organosilanes compounds have been described in the prior art (Moitra et al, Chem. Commun., 2010, 46, 8416-8418; Burglova et al, J. Org. Chem., 2011, 76, 7326-7333).
