摘要：

Dimethoxy(trisyl)borane A3(CB(OMe)2 (1a: "trisyl" = A3C; A = Me3Si) can be hydridated to the borate (Et2O)2LiH3BCA3 (2a) by the action of LiAlH4 in ether. Hydro(trisyl)boranes A3C-BH(OR) (3a-d; R = Me, Et, i-Pr, H) are formed from 2a with ROH by oxidative removal of two H-atoms. The removal of only one H-atom from 2a can be achieved with either Me3NHCl or I2, yielding bis(trisyl)di-borane(6) (A3CBH2)2 (4; space group P1; molecular symmetry Ci), which forms the adduct A3CBH2 · PMe3 (5) with PMe3. Starting from 2a, the borates (tmeda)LiH3BCA3 (2b) and ClZr(H3BCA3)3 · 0.5Et2O (2c; space group P21/c) can be prepared by the reaction with tmeda and ZrCl4, respectively; the trisylborate groups are bonded to the Zr atom via H3-triple bridges. © 1990.
