A sulfur mimic of 1,1-bis(diphenylphosphino)methane: a new ligand opens up.
نویسندگان
چکیده
A simple method for synthesizing diphosphine monosulfide species was developed utilizing lithium sulfide and chlorophosphine starting materials. This afforded 1,1,2,2-tetraphenyldiphosphine monosulfide (1), as well as 1,1,2,2-tetracyclohexyldiphosphine monosulfide (2), which could be used as convenient ligand precursors. Upon addition of 1 or 2 to the ruthenium compound Ru(C5Me5)(cod)Cl, the diphosphine monosulfides rearranged to give bidentate bis(ditertiaryphosphino)thioether ligands in Ru(C5Me5)(PPh2SPPh2)Cl (3) and Ru(C5Me5)(PCy2SPCy2)Cl (4).

The asymmetric unit of the title compound, [Pt(C(25)H(22)P(2))(C(27)H(26)P(2))]Br(2) or [Pt(dppm)(dppp)]Br(2), where dppm is bis(diphenylphosphino)methane and dppp is 1,3-bis(diphenylphosphino)propane, consists of a discrete [Pt(dppm)(dppp)](2+) cation and two Br(-) anions at van der Waals distances. This is the first reported platinum(II) complex containing both dppm and dppp ligands. Noticeab...
متن کاملA Self-Assembled Electro-Active M8L4 Cage Based on Tetrathiafulvalene Ligands
Two self-assembled redox-active cages are presented. They are obtained by coordination-driven self-assembly of a tetra-pyridile tetrathiafulvalene ligand with cis-M(dppf)(OTf)₂ (M = Pd or Pt; dppf = 1,1'-bis(diphenylphosphino)ferrocene; OTf = trifluoromethane-sulfonate) complexes. Both species are fully characterized and are constituted of 12 electro-active subunits that can be reversibly oxidi...

The enthalpy for the substitution reaction cis-[PdRf(2)(THF)(2)] + 2 L -->cis-[PdRf(2)L(2)] + 2THF (THF = tetrahydrofuran) has been measured in THF by calorimetric methods for Rf = 3,5-dichloro-2,4,6-trifluorophenyl, L = PPh(3), AsPh(3), SbPh(3), PMePh(2), PCyPh(2), PMe(3), AsMePh(2), or L(2) = dppe (1,2-bis(diphenylphosphino)ethane), dppf (1,1'-bis(diphenylphosphino)ferrocene). The values dete...
متن کاملChiral biphenyl diphosphines for asymmetric catalysis: stereoelectronic design and industrial perspectives.
Two original chiral diphosphines, SYNPHOS and DIFLUORPHOS, have been synthesized on multigram scales. Their steric and electronic profiles have been established in comparison with the commonly used 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl and 6,6'-dimethoxy-2,2'-bis(diphenylphosphino)-1,1'-biphenyl ligands. A screening study of the four ligands in Ru(II)-catalyzed asymmetric hydrogenation of...
متن کاملRedox Chemistry of Gold(I) Phosphine Thiolates: Sulfur-Based Oxidation
The redox chemistry of mononuclear and dinuclear gold(I) phosphine arylthiolate complexes was recently investigated by using electrochemical, chemical, and photochemical techniques. We now report the redox chemistry of dinuclear gold(I) phosphine complexes containing aliphatic dithiolate ligands. These molecules differ from previously studied gold(I) phosphine thiolate complexes in that they ar...
