Molecular Structure of the Solvated Proton in Isolated Salts. Short, Strong, Low Barrier (SSLB) H-bonds

“…Carborane anions, [62][63][64] protonated arene salts, 45,58 and H9O4 + salts 27 were prepared as previously described. Solvents were dried by standard methods.…”

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

“…The crystals of the silver salt of 12-fluoro-1-carba-closo-dodecaborate anion {Ag(η 2 -benzene) 2 The silver salt of 12-bromo-1-carba-closo-dodecaborate anion, Ag[1-CB11H11-12-Br], was prepared using the standard metathesis approach [92]. The crystals {Ag(η 1 -benzene) [1-CB11H11-12-Br]}n were obtained by crystallization from benzene.…”

“…The silver atom has a formal coordination number of four, bonding to tree carborane anions and one benzene molecule. Two [1-CB11H11-12-Br] − anions are coordinated to the silver atom via BH groups (Ag…H(B) distances of 2.20 and 2.27 Å) and the third anion is coordinated by the bromine atom (Ag…Br(B) distance of 2.642 Å), the benzene molecule is coordinated to the silver atom in a η 1 -fashion with Ag-C distance of 2.485 Å (Figure 65) [92]. The silver salt of 12-bromo-1-carba-closo-dodecaborate anion, Ag[1-CB11H11-12-Br], was prepared using the standard metathesis approach [92].…”

Four Decades of Organic Chemistry of closo-Boranes: A Synthetic Toolbox for Constructing Liquid Crystal Materials. A Review

“…Carborane and monocarbaborate-derived anions are highly nucleophilic and react with a wide range of C-electrophiles providing a convenient route to C-C bonds. The C-lithium reagents are particularly useful in the alkylation with primary iodides and bromides and carboxylation reactions described for carboranes including para-carboranes 6 (refs 20,82,83 ) and 10 (refs 58,84,85 ), and also for monocarbaborates 2 (refs 67,86 ) and 8 (ref. 61 ).…”

“…50), typically obtained in high yields 143,145 . The regioselectivity of mercuration of C-monosubstituted carboranes has not been investigated 145 Mercuration of monocarbaborate 2 results in the 12-mercurio derivative obtained in 72% yield 86 and its 1-NMe 3 derivative 51 was mercurated to form 52 in 37% yield 146 .…”
