Transition metal complexes based on carboranyl ligands containing N, P, and S donors: Synthesis, reactivity and applications

Monomeric phosphinoboranes

“…The P O B complex 76 was found to be much more active than its P B and P O C counterparts 75 and [RhCl( i Pr 2 POPh)(1,5-cod)] in hydrolsilylation. In hydroboration, similar activities were observed Ligands with carborane substituents are known for a variety of donor atoms [82,83]. The bonding properties of these carboranyl ligands are strongly dependent on the vertex to which the donor atom is bonded [84,85].…”

Synthesis and characterization of carboranyl Schiff base compounds from 1-amino- o -carborane

“…It is anticipated that these mono-substituted carboranyl Schiff-base compounds might act as nitrogen-containing carboranyl ligands [16] towards metal complex species under suitable conditions, which is currently under study in our lab. Further attempts to prepare 1,2-diamino-o-carborane (5) by modified or other novel procedures are also expected.…”

Synthesis, structure, and mechanism of half-sandwich ruthenium complexes based on ortho-carborane-1,2-dithiolate ligand and alkyne alcohol

“…Several approaches have been developed to con struct stable 1,2 dicarba closo dodecaborane deriva tives. The common strategies previously employed include polycarborane architectures containing two or more 1,2 dicarba closo dodecaborane 1,2 dichalco genolate units from 16e half sandwich Cp*M(E 2 C 2 B 10 H 10 ) (Cp* = η 5 C 5 Me 5 , M = Co, Rh, Ir, E = S, Se) complexes [5][6][7], the reactions of 16e complexes containing an o carborane 1,2 dichal cogenolate ligand with monodentate Lewis bases or alkynes [8][9][10]. From the preliminary studies it becomes clear that the products depend on the metal center, the chalcogen element and the used alkyne.…”
