Abstract:
The first representative of the Janus cube with hydrogen substituents was obtained from all-cis-[BuiSiO(OH)]4 by its capping with HSiCl3 followed by gentle hydrolysis causing internal condensation. The compound has an extremely low maximum loss temperature, which is approximately halfway between H8Si8O12 and (octaisobutyl)octasilsesquioxane.
