“…In the last few years, a fascinating new strategy emerged which makes use of supramolecular interactions for the construction of cis-chelating diphosphines [185][186][187][188][189][190][191][192][193][194][195][196][197][198][199][200]. The challenging synthesis of trans-chelating diphosphines has also been approached with this methodology.…”

Ion pairs containing N-substituted derivatives of 1,3,5-triaza-7-phosphaadamantane (pta-R; R= benzyl, butyl, hexyl) as cations and monosulfonated triphenylphosphine (mtppms) as anion were synthetized and characterized (including X-ray diffraction, too). These ion pairs act as bidentate phosphorus ligands in reactions with [(η 6 -C 10 H 14 )RuCl 2 ] 2 , yielding mononuclear or dinuclear half sandwich Ru(II) complexes. A bisphosphine 3 of good watersolubility was synthesized in reaction of pta with 1,4-bis(chloromethyl)benzene and used for the synthesis of the water-soluble dinuclear complex [{(η 6 -C 10 H 14 )RuCl 2 } 2 (μ-3)]Cl 2 .

“…[114] The thus formed phosphine ion pair increased www.chemeurj.org the tendency towards formation of hetero-bisphosphine complexes, in which the phosphine assembly can be regarded as a heterobidentate ligand. The described associative interaction allows both cis (33) and trans (34) coordination in square-planar transition-metal complexes (Scheme 11).…”

The effects of introducing ionic functionalities in phosphine ligands on the coordination chemistry of these ligands and the catalytic behavior of the corresponding metal complexes are reviewed. The steric and electronic consequences of such functionalizations are discussed. Apart from these steric and electronic effects, the presence of charged groups often leads to additional, supramolecular interactions that occur in the second coordination sphere of the metal complex, such as intramolecular, interligand hydrogen bonding and Coulombic repulsion. These interactions can significantly alter the behavior of the phosphine ligand in question. Such effects have been observed in phosphine-metal association/dissociation equilibria, ligand substitution reactions, and stereoisomerism in phosphine-metal complexes. By drawing general conclusions, this review offers an insight into the coordination and catalytic behavior of phosphine ligands containing ionic functionalities and their corresponding metal complexes.
