Catalyseurs pour la transformation de polydimethylsilanes en polycarbosilanes

, p. 125 - 132 (1988)
The conversion of polydimethylsilanes into the corresponding polycarbosilanes has been studied using liquid monomeric catalysts such as B(OR)3 (R = Me, Pr, SiMe3) or the B-N bonded compounds: Me2BN(SiMe3)2 and B(NEt2)3.Using this route it is possible to obtain polycarbosilanes which are more stable than the Mark III synthesized by the Yajima route and have a smaller polydispersity.These precursors obtained at 380-400 deg C do not require the use of an autoclave.

Paragraph 0016-0017, (2017/08/31)
The invention discloses a synthesis method of boric acid tris(trimethylsilyl)ester, wherein the synthesis method comprises the steps: mixing boric acid and hexamethyldisilazane, then adding a catalyst sulfonic acid type cation dry hydrogen resin, next heating up to 60-80 DEG C, vacuumizing in a reaction process, adsorbing ammonia gas generated in the reaction, after the reaction is finished, cooling, filtering, and thus obtaining a filtrate boric acid tris(trimethylsilyl)ester crude product and a filter residue; and then carrying out reduced pressure rectification on the filtrate, and collecting a fraction to obtain the high-purity boric acid tris(trimethylsilyl)ester. The synthesis method simplifies the technological process of synthesis and rectification operations, the catalyst can be reused, the product yield reaches more than 85%, and the production cost is reduced.
