A catalytic study of water dispersed gold nanoparticles for the hydrolytic oxidation of diorganosilanes-: En route formation of a Pickering catalyst and synthesis of tetraorganodisiloxane-1,3-diols

Water-dispersed gold nanoparticles decorated with an amphiphilic cyclotetrasiloxane scaffold hold promise for the catalytic transformation of diorganosilanes to tetraorganodisiloxane-1,3-diols, (RR1SiOH)2O [R = Me or Ph R1 = Ph, cyclo-Hex] via en route formation of a Pickering emulsion. The recognition ability of these compounds toward Cl- ions reveals 2?:?1 receptor-anion complexation.

Procedures for the preparation of silanols

Two procedures are described for the preparation of silanols and silanediols from the corresponding chlorosilanes.The first procedure, a two-phase hydrolysis-extraction process, is- particularly convenient and suited to the preparation of a wide range of mono-silanols.Hydrolysis of dichlorosilanes by this procedure gives varied results depending on the structure of the dichlorosilane and specific reaction conditions.The second procedure, a modification of a published procedure, is especially beneficial for the preparation of silanols and silanediols prone to undergo self-condensation.

Novel n[meth)allyloxy(meth)allylphenyl]maleimides and thermosetting imido copolymers prepared therefrom

Novel N-[(meth)allyloxy-mono-/di(meth)allylphenyl]maleimides, in admixture with at least one N-[(meth)allyloxyphenyl]maleimide, are reacted with at least one bismaleimide, and optionally a hydroxylated organosilicon compound, in the presence of an imidazole compound, to obtain mechanically improved thermosetting imido copolymerizates well adapted for the production of, e.g., coatings, adhesive bondings, laminates and composites.
