A convenient and clean synthetic method for borasiloxanes by Pd-catalysed reaction of silanols with diborons

Selective O-borylation of silanols with diborons took place in the presence of Pd catalysts to give the corresponding boryl silyl ethers in high yields.

METHOD FOR PRODUCING BORYL SILYL ETHER

PROBLEM TO BE SOLVED: To provide a method for producing boryl silyl ether that can efficiently produce boryl silyl ether. SOLUTION: In the presence of a catalyst containing a group 10 element and/or a group 11 element in the periodic table, the reaciton between silanol and diborane makes it possible to produce efficiently boryl silyl ether.

Ru0-catalyzed coupling of vinylboronates with silanols, disilanols, and disiloxanediols: A selective route to borasiloxanes

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 Ru0 complexes (mainly Ru 3CO12) is described. The method leads to the formation of special compounds with a B-O-Si inorganic framework. When Ru0 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 Ru0 with triethylsilanol and vinylboronate. A new, selective approach to borasiloxanes through catalytic O-borylation was developed. Vinylboronates are coupled with silanols, silanediols, and siloxanediols, which yield borasiloxanes as the only products with the evolution of ethylene. A mechanism for this Ru3(CO)12-catalyzed transformation is also proposed. Copyright
