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.

O-Metalation of silanols and POSS silanols over Amberlyst-15 catalyst: A facile route to unsymmetrical siloxanes, borasiloxanes and germasiloxanes

A simple and highly practical Amberlyst-catalyzed direct O-metalation of silanols, POSS silanols and alkoxysilanes under mild conditions is proposed. This protocol can be applied to the synthesis of a wide range of important organosilicon derivatives such as siloxanes, germasiloxanes, borasiloxanes and functionalized silsesquioxanes. It is worth noting that Amberlyst-15 can be reused for further experiments and its catalytic activity in this process is well-preserved for several recycling steps.

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.

Ruthenium-catalysed multicomponent synthesis of borasiloxanes

We present the selective atom economical synthesis of borasiloxanes using a multi-component approach directly by the one-pot ruthenium catalysed reaction of boranes, silanes and water.

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

Compounds containing B-O-X bonds (X=Si, Ge, Sn, Pb): Part 5. Synthesis of chain borosilicates containing B:Si ratios of 2:1, 2:2, 2:3 and 2:4. Crystal structure of (O-CMe2CH2CHMe-O-B-O)2SiBut 2

Twelve borosilicates with the general formula O-Y-O-B-O-(SiPh2O)n-B-O-Y-O (where n=1, 2, 3 or 4; Y=one of the organic groups CMe2CMe2, CMe2CH2CHMe, CMe2CH2CMe2 or CHPriCMe2CH2) were prepared. Three synthetic routes were investigated, including a one-pot self-assembly reaction of two equivalents each of boric acid, silanediol and organic diol. The probable sequence for this reaction is discussed. The borosilicates were either solids or viscous liquids and were colourless. They formed cyclosiloxane species when thermally decomposed or reacted with either water or potassium trimethylsilanolate. They were unreactive to triethylamine, di-iso-propylamine, pyridine or ethylenediamine. The di-tert-butyl species (O-CMe2CH2CHMe-O-B-O)2SiBut 2 was prepared and structurally characterised using X-ray techniques. The parameters associated with the B-O-Si bonds were a B-O-Si angle of 141.5(2)° and B-O and Si-O distances of 1.360(4) and 1.625(2) A, respectively. Elsevier Science Ltd.

Triphenylsiloxy and Diphenylsiladioxy Derivatives of Boron

Tris(triphenylsiloxy)borane, phenyl bis(triphenylsiloxy)borane, 2-triphenylsiloxy-1,3,2-dioxa-borolanes, -borinanes, -borole and -borin and diphenyl bis(1,3,3,2-dioxa-borolane-2-oxy)silanes have been synthesized by various routes and the reactivity of Si-O-B linkage has been compared with that of Ge-O-B and Sn-O-B linkages.Tris(triphenylsiloxy)-borane reacts with acetyic acid by cleavage of Si-O bond to give triphenylsilyl acetate and boric acid. 2-Triphenylsiloxy-1,3,2-benzodioxaborole forms 1:1 addition complexes with pyridine, triethylamine and aniline.Condensation of diphenylsilane diol with boric acid, tri(isopropoxy)borane or phenyldihydroxyborane yields cyclic derivatives.
