A new highly selective method for the synthesis of borasiloxanes through the O ‐borylation of silanols, disilanols, and disiloxanediols with vinylboronates in the presence of Ru 0 complexes (mainly Ru 3 CO 12 ) is described. The method leads to the formation of special compounds with a B–O–Si inorganic framework. When Ru 0 complexes are used as a catalyst, no vinylboronate homocoupling is observed. A mechanism for this transformation is proposed on the basis of stoichiometric reactions of Ru 0 with triethylsilanol and vinylboronate.
