The inter-triangular diphosphine bridge in [AuMn2(CO)8(mu-PPh2)]2(mu-P-P) turns into an intra-triangular one as it undergoes amine-oxide-promoted decarbonylation to give (P-P)-AuMn2(CO)7(mu-PPh2) (P-P = Ph2P-X-PPh2; X = (CH2)n, Fe(C5H4)2; n = 1-4) in the presence of the corresponding free diphosphine. The resultant triangular cluster contains a heterometallic Au-Mn bond overbridged by all common diphosphines attempted, including dppf (X = Fe(C5H4)2) and dppp (n = 3). The Au-Mn bond supported by dppf (2.6797(7) A) is shorter than that supported by dppe (n = 2) (2.756(2) A) or dppp (2.7643(4) A).

A study has been made of the possibility of increasing the stability of the 1,1?-bis(diphenylphosphino)ferrocenium monocation by introduction of appropriate substituents into the cyclopentadienyl ligands. The electrochemical behaviour of a series of 1,1?-bis(diphenylphosphino)ferrocenes bearing substituents with a range of electronic properties has been examined. The results reveal that, the higher the electron-donating ability of the substituents, the longer is the lifetime of the corresponding 1,1?-bis(diphenylphosphino)ferrocenium monocation. However, no stable ferrocenium cation has been obtained; mass spectrometry shows that mixtures of mono- and di-bis(diphenylphosphine)oxides are ultimately formed as products resulting from decomposition of the initially electrogenerated 1,1?-bis(diphenylphosphino)ferrocenium species.

Reference of 12150-46-8. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 12150-46-8, Name is 1,1-Bis(diphenylphosphino)ferrocene. In a document type is Article, introducing its new discovery.

Copper(I) forms mixed ligand coordination compounds with the stable, paramagnetic bipyridine analogue, 1,5-dimethyl-3-(2-pyridyl)-6-oxoverdazyl (pyvd) and a variety of monodentate and bidentate phosphine ligands. These compounds were characterized in solution by titration, UV-vis spectra, ESR spectra and electrospray mass spectrometry. Coordination of the phosphine gives a metal-ligand charge transfer transition in the UV-vis that is red shifted by more electron donating phosphines. ESR indicates that spin density on copper increases, both with strongly electron donating phosphines and with weakly basic phosphite ligands. This can be explained by the presence of two different orbital interactions: with more donating phosphines the interaction is predominantly through the filled copper(I) d-orbitals, but with weakly donating phosphite ligands the interaction is through an empty copper(I) p-orbital. The differing spin transfer mechanisms may have implications in the design of molecular magnetic systems.

[Pt(CSe3)(PR3)2] (PR3 = PMe3, PMe2Ph, PPh3, P(p-tol)3, 1/2 dppp, 1/2 dppf) were all obtained by the reaction of the appropriate metal halide containing complex with carbon diselenide in liquid ammonia. Similar reaction with [Pt(Cl)2(dppe)] gave a mixture of triselenocarbonate and perselenocarbonate complexes. [{Pt(mu-CSe3)(PEt 3)}4] was formed when the analogous procedure was carried out using [Pt(Cl)2(PEt3)2]. Further reaction of [Pt(CSe3)(PMe2Ph)2] with [M(CO)6 (M = Cr, W, Mo) yielded bimetallic species of the type [Pt(PMe2Ph) 2(CSe3)M(CO)5] (M = Cr, W, Mo). The dimeric triselenocarbonate complexes [M{(CSe3)(eta5-C 5Me5)}2] (M = Rh, Ir) and [{M(CSe 3)(eta6-p-MeC6H4 iPr)}2] (M = Ru, Os) have been synthesised from the appropriate transition metal dimer starting material. The triselenocarbonate ligand is Se,Se’ bidentate in the monomeric complexes. In the tetrameric structure the exocyclic selenium atoms link the four platinum centres together.

The large family of mononuclear molybdenum and tungsten enzymes all possess the special ligand molybdopterin (MPT), which consists of a metal-binding dithiolene chelate covalently bound to a pyranopterin group. MPT pyran cyclization/scission processes have been proposed to modulate the reactivity of the metal center during catalysis. We have designed several small-molecule models for the Mo-MPT cofactor that allow detailed investigation into how pyran cyclization modulates electronic communication between the dithiolene and pterin moieties and how this cyclization alters the electronic environment of the molybdenum catalytic site. Using a combination of cyclic voltammetry, vibrational spectroscopy (FT-IR and rR), electronic absorption spectroscopy, and X-ray absorption spectroscopy, distinct changes in the Mo?O stretching frequency, Mo(V/IV) reduction potential, and electronic structure across the pterin-dithiolene ligand are observed as a function of pyran ring closure. The results are significant, for they reveal that a dihydropyranopterin is electronically coupled into the Mo-dithiolene group due to a coplanar conformation of the pterin and dithiolene units, providing a mechanism for the electron-deficient pterin to modulate the Mo environment. A spectroscopic signature identified for the dihydropyranopterin-dithiolene ligand on Mo is a strong dithiolene ? pterin charge transfer transition. In the absence of a pyran group bridge between pterin and dithiolene, the pterin rotates out of plane, largely decoupling the system. The results support a hypothesis that pyran cyclization/scission processes in MPT may function as a molecular switch to electronically couple and decouple the pterin and dithiolene to adjust the redox properties in certain pyranopterin molybdenum enzymes.

Searching for prospective agents against infectious diseases, four new ferrocenyl derivatives, [M(L)(dppf)4](PF6), with M = Pd(II) or Pt(II), dppf = 1,1?-bis(dipheny1phosphino) ferrocene and HL = tropolone (HTrop) or hinokitiol (HHino), were synthesized and characterized. Complexes and ligands were evaluated against the bloodstream form of T. brucei, L. infantum amastigotes, M. tuberculosis (MTB) sensitive strain and MTB clinical isolates. Complexes showed a significant increase of the anti-T. brucei activity with respect to the free ligands (>28- and >46-fold for Trop and 6- and 22-fold for Hino coordinated to Pt-dppf and Pd-dppf, respectively), yielding IC50 values < 5 muM. The complexes proved to be more potent than the antitrypanosomal drug Nifurtimox. The new ferrocenyl derivatives were more selective towards the parasite than the free ligands. The Pt compounds were less toxic on J774 murine macrophages (mammalian cell model), than the Pd ones, showing selectivity index values (SI = IC50 murine macrophage/IC50 T. brucei) up to 23. Generation of the {M-dppf} compounds lead to a slightly positive impact on the anti-leishmanial potency. Although the ferrocenyl derivatives were more active on sensitive MTB than the free ligands (MIC90 = 9.88?14.73 muM), they showed low selectivity towards the pathogen. Related to the mechanism of action, the antiparasitic effect cannot be ascribed to an interference of the compounds with the thiol-redox homeostasis of the pathogen. Fluorescence measurements pointed at DNA as a probable target of the new compounds. [Pt(Trop)(dppf)](PF6) and [Pt(Hino)(dppf)](PF6) could be considered prospective anti-T. brucei agents that deserve further research.
