Another example of carborane based trianionic ligand: Syntheses and catalytic activities of cyclohexylamino tailed ortho-carboranyl zirconium and titanium dicarbollides

Carbaboranes as Pharmacophores: Properties, Synthesis, and Application Strategies

“…Almost uninvestigated is the ring-opening reaction of aziridines to obtain ethylamine-modified carbaboranes as an alternative to classical lithium halide elimination . One literature source described the reaction of lithiated 1-phenyl- ortho -carbaborane with bicyclic 7-azabicyclo[4.1.0]heptane to give 1-phenyl-2-(2′-aminocyclohexyl)-1,2-C 2 B 10 H 10 …”

Coordination Ability of 10-EtC(NHPr)=HN-7,8-C2B9H11 in the Reactions with Nickel(II) Phosphine Complexes

“…One of the most interesting and promising tasks in this area is the synthesis of heterobifunctional nido-carborane-based ligands, that can give a firm bound to capture the metal center along with a weak bond, temporarily protecting a metal coordination site. This allows users to obtain labile complexes of transitional metal representing a promising new type of catalysts [5][6][7][8][9][10] and molecular switches [11,12]. There are several examples of such stable metal complexes based on nido-carborane with a side substituent coordinated through oxygen or nitrogen [5][6][7][8][13][14][15].…”

The utility of such bifunctional ligand systems with the nitrogen donor atom in the side chain has been demonstrated by the complexation of [7-Me 2 NCH 2 -7,8-C 2 B 9 H 11 ]with metals such as nickel [16], iron [17], rhuthenium [17], titanium, zirconium, and hafnium [18,19].…”
