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.

Abstract

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.
