A commercially available and stable ruthenium dodecacarbonyl catalyst (Ru3(CO)12) allows very efficient and convenient access to functionalized silsesquioxanes (SQs) containing siloxane moiety (Si–O–Si) via dehydrogenative coupling of POSS-silanols with hydrosilanes. With the aid of SiH-containing silsesquioxanes, an unprecedented one-pot procedure has been revealed, and the usefulness of this approach was demonstrated by the synthesis of various derivatives via O-silylation, as well as CC and CN hydrosilylation.

We report a highly effective metal-free catalytic procedure for the functionalization of silsesquioxanes via dehydrocoupling of various POSS silanols with hydrosilanes in the presence of commercially available tris­(pentafluorophenyl)­borane B­(C6F5)3. This approach enables the unprecedented one-pot synthesis of valuable silsesquioxane derivatives under mild conditions, with no corrosive byproducts formed in the process.

Pincer cobalt complexes based on a triazine backbone have been used as efficient catalysts for the hydroboration reaction of alkenes. The presented protocol shows unique selectivity distinguishing a vinylsilyl from another alkenyl or alkynyl groups.
