Polydentate Phosphines: Their Syntheses, Structural Aspects, and Selected Applications

cis and trans influences on [Pt(SRF)(triphos)]+ complexes (SRF = polyfluorobenzothiolate)

“…All platinum-phosphorous bond lengths and angles are in agreement with previously reported values. [14][15][16] The Pt1-P2 bond is shorter than the two mutually trans platinum-phosphorous bonds due to the double chelate effect, in agreement with previously reported chloride complexes [PtCl(triphos)]X (X = Cl À or CuCl 2…”

“…All platinum-phosphorous bond lengths and angles are in agreement with previously reported values. [14][15][16] The Pt1-P2 bond is shorter than the two mutually trans platinum-phosphorous bonds due to the double chelate effect, in agreement with previously reported chloride complexes [PtCl(triphos)]X (X = Cl À or CuCl 2 À ). 13a The thiolate ligand, SR F À , occupies the platinum fourth coordination site with the expected bond lengths and angles for platinum-thiolate complexes.…”

Direct, One-Pot Syntheses of MOFs Decorated with Low-Valent Metal-Phosphine Complexes

“…For example, in earlier studies, Cohen developed the use of MOFs with pendant amines for the postsynthetic installation of reactive metal sites and Yaghi demonstrated low-valent metal coordination in carbene-decorated MOFs . Our ongoing approach in this area is to utilize phosphine- and arsine-based MOFs for the installation of low-valent metal complexes, given that such ligands are ubiquitous in molecular catalysis. − Our group and those of Wade and Lin have shown that MOF building blocks based on preformed bis­(phosphine) , and PCP-pincer ,,− complexes can be used to assemble MOF structures containing reactive metal sites. However, we increasingly disfavor this approach because the organic chemistry required to prepare the molecular precursors is often arduous and low-yielding.…”

Synthesis and X-ray structural characterization of mono(aminophosphine) derivatives of molybdenum hexacarbonyl, Mo(CO)5L {L = P(NC5H10)3, P(Ph)(NC4H8O)2 or P(Ph){N(i-C3H7)2}(NC4H8O)}

“…The donor-acceptor nature of phosphines as ligands has been extensively studied [1][2][3][4][5][6][7][8]. The use of tertiary phosphines, in the substitution reactions of metal carbonyls, especially of M(CO) 6 [M = Cr, Mo and W], has served both fundamental and applied interests [9][10][11][12].…”
