A convenient method for the synthesis of borasiloxanes from silanes and pinacolboranes using Cu3(BTC)2 as a heterogeneous catalyst in acetonitrile at 70 °C is reported. This procedure is more convenient than Ru and Pd based homogeneous catalysts because it avoids the use of noble metals, easy handling of starting materials and the catalyst can be reused.

Paragraph 0019-0020; 0025-0028, (2021/06/21)
The invention discloses a preparation method of a borosiloxane compound. The preparation method comprises the following steps: 1) with borane, silane and water as starting raw materials, adding a photosensitizer and an organic solvent into a reaction container, carrying out a stirring reaction under the irradiation of blue light, and stopping stirring when it is detected that the reaction raw material borane completely disappears through in gas chromatographic detection so as to obtain a reaction solution; and 2) removing a volatile solvent from the reaction solution, conducting extracting with n-hexane, dehydrating and drying an obtained organic phase with anhydrous sodium sulfate, and conducting concentrating under reduced pressure to obtain the target product. According to the method for preparing borosiloxane, traditional precious metal catalysis is replaced with blue light catalysis for the first time; borane, silane and water are used as raw materials, the reaction occurs along with release of molecular hydrogen, atom economy is high, waste is avoided, so production cost is greatly reduced, and remarkable social benefits and economic benefits are achieved; and in addition, the method is mild in catalysis conditions, simple in catalysis system, high in reaction selectivity, high in safety, high in synthesis efficiency and worthy of popularization and application.

Ito, Masaki,Itazaki, Masumi,Nakazawa, Hiroshi
supporting information, p. 6183 - 6186 (2014/05/20)
Selective B-O-Si bond formation was achieved in the reaction of bisboryloxide O(Bpin)2 (pin = (OCMe2)2)/ boroxine (MeBO)3 system with tertiary silane R3SiH in the presence of stoichiometric water and a catalytic amount of [M](CO)5 ([M] = Mo(CO), W(CO), Fe) to give boryl silyl ethers. Moreover, this reaction can be applied to various hydrosilanes (disilyl compounds and secondary silanes) and hydrogermane. Some of the boryl silyl ethers thus formed were confirmed by X-ray analysis.
