Simplified synthesis of decaborane(14) from sodium tetrahydroborate via tetradecahydroundecaborate(1-) ion

[Me3Si][R‐CB11F11]—Synthesis and Properties

“…[22,23] This compound was treated with NaH (29.1 g, 1.21 mol; Fluka, ca. 60 %, washed with n-pentane before use) in dimethoxyethane (200 mL) at 0 8C to afford Na 2 [B 11 H 13 ].…”

Carba‐closo‐dodecaborate Anions with Cluster Carbon–Phosphorous Bonds

“…Elemental analysis (C, H, N) were performed with a Euro EA3000 instrument (HEKA-Tech, Germany). [39] according to a modification [40] of a literature procedure. [41] Cs[closo-1-13 CB 11 H 12 ] was prepared similar to a published multi-step procedure starting from K 13 CN and decabor-ane (14).…”

Palladium and Rhodium Complexes with Planar-Chiral Carborane Ligands

“…Using the well-established procedure for the resolution of racemic bis(phosphanes) via internally diastereomeric palladium complexes, [12,13] it was possible to resolve the rac-7diphenylphosphanyl-8-phenyl-7,8-dicarba-nido-undecaborate anion. The diastereomers 3R-R and 3R-S (Scheme 2) were synthesized from 2e and di-µ-chlorobis{(R)-2-[1-(dimethylamino)ethyl]phenyl-C,N}palladium [14] in CH 2 Cl 2 at 10°C.…”
