1,1'‐Bis(diphenylphosphino)ferrocene ‐‐‐ Coordination Chemistry, Organic Syntheses, and Catalysis

Reactivity of [Pt(dppf)Cl2] toward Simple Organic Thiolates: Preparation and Structure of [Pt(dppf)(SPh)2], [Pt(dppf)(S-n-Pr)2], and [Pt(dppf)(SCH2CH2CH2S)] (dppf = Fe(η5-C5H4PPh2)2)

“…The dppf ligand is a well-known redox-active ligand, and its complexes are expected to exhibit a ferrocene-centered oxidation process, together with the additional redox processes at other metal centers in the molecule. 1 The free dppf ligand in dichloromethane exhibits one irreversible, ferrocene-centered oxidation. 14 Cyclovolatmmograms of compounds 1-3 are shown in Figure 4.…”

“…1 In particular, group 10 metal-dppf compounds are the most intensively studied family with more than 40 crystal structures having been reported. 2 Very recently, several reports on the group 10 metal-dppf compounds containing metal-sulfur bonds occurred in the literature, in which the sulfur-donating ligands are thiocarboxylate (SC(O)Me), 3 homochalogenide {1,2-benzenedithiol (HSC 6 H 4 SH), 3,4-toluenedithiol (HSC 6 H 3 MeSH), and 3,6-dichlorobenzenedithiol (HSC 6 H 2 Cl 2 SH)} or mixed-chalcogenide {2-mercaptophenol (HSC 6 H 4 OH) and thionicotinic acid (HSC 5 -H 3 NCO 2 H)}, 4 and crown thioether 1,4,7-trithiacyclononane (9S3).…”

Mass spectral behavior of some homoleptic and mixed aryldichalcogenide bis(diphenylphosphino)ferrocenenickel(II), palladium(II), and platinum(II), and bis(diisopropylphosphino)ferrocenepalladium(II) complexes

“…The absence of this ion in the EI spectra is most likely due to a weak phosphorus-Ni bond which fragments after the formation of the [dppfNi] ϩ ion. A similar explanation is offered for the irreversibility of redox behavior of Ni(dppf)Cl 2 as oxidation leads to the decomposition of the oxidized species [13]. The fragment ions at m/z ϭ 554 and m/z ϭ 477 were also observed in the FAB spectra, though their intensities were low.…”

[1,1'-Bis(methylphenylphosphino)ferrocene-P,P'](pentane-2,4-dionato-O,O')palladium Tetrafluoroborate

“…1) possesses a square planar Pd u centre. The phosphine ligand is closely related to the well known complex 1,1'-bis(diphenylphosphino)ferrocene, Fe(C5H4PPh2)2 (dppf), for which much structural data are available (Gan & Hor, 1995). The ferrocene skeleton of the rac-mppf ligand exhibits slight distortions from idealized geometry, as is commonly observed for complexes of dppf.…”
