Regioselective Fluorination of CB11H12-. New Weakly Coordinating Anions

Metal Complexes with Very Large Dipole Moments: the Anionic Carborane Nitriles 12-NC–CB11X11– (X = H, F, CH3) as Ligands on Pt(II) and Pd(II)

“…59,60 Interestingly, the fluorination of 2 (Scheme 5) proceeds ∼30% faster than the fluorination of the parent Cs[HCB 11 H 11 ]. The product of fluorination [1-H-12-CN-CB 11 F 10 ] (23) was isolated as an NHMe 3 + salt.…”

Silver and Copper Complexes with closo-Polyhedral Borane, Carborane and Metallacarborane Anions: Synthesis and X-ray Structure

“…The silver atom has a formal coordination number of four, bonding to two carborane anions and two benzene molecules. Both [1-CB11H11-12-F] − anions are coordinated to the silver atom via BH groups (Ag…H(B) distances of 2.18 and 2.28 Å), the benzene molecules are coordinated to the silver atom in a η 2 -fashion ( Figure 64) [91]. Significantly, there is no interaction between the silver ion and the fluorine atom.…”

Chemistry of the Carba-closo-dodecaborate(−) Anion, CB11H12-

“…In the salt of the 12-bromo-substituted anion,[Ag(C 6 H 6 )] [175], 16 the silver ion interacts with three different carborate anions through Br-B (12). In the similar 12-fluoro complex, 38 the silver coordinates to two B-H hydrogen atoms of two carborate anions and no interaction between silver and fluorine is observed. Fluorine-containing anions seem to be generally more weakly coordinating than bromine-containing anions.…”
