(2a–e and 3a–e) in a seamless way, thereby leading to a novel
class of unsymmetrically functionalized silsesquioxane deriva-
tives. Fourteen new products were obtained in high yields using
this straightforward pathway. They were fully characterized
using various analytical techniques.

In light of the results described above, the silylative coupling
reaction should now be regarded as a promising catalytic tool
for grafting two distinct styryl groups onto a DDSQ scaffold. It
therefore nicely complements previous strategies based on
hydrosilylation and Heck reactions for the unsymmetrical
functionalization of cubic T8 structures.10,11 Because the compounds
obtained in this study may be subjected to further independent
transformations on both ends, the method has great potential for
fine-tuning the physicochemical properties of advanced materials
based on DDSQ core units and for expanding their application field.
