N2 - Radical initiated hydrobromination and methoxycarbonylation using a Pd(0) complex have been used to convert octavinylsilsesquioxane to species functionalised with alkyl bromide and linear methyl propanoate groups on all eight reactive sites, respectively. The two new molecules, 1,3,5,7,9,11,13,15-octakis[ethylbromide]octasiloxane and 1,3,5,7,9,11,13,15-octakis[methylpropanoate]octasiloxane, have been characterised using NMR (H-1, C-13 and Si-29) and IR spectroscopy, elemental analysis and single crystal X-ray diffraction.
