Room-temperature reduction of sulfur hexafluoride with metal phosphides

Upon treatment with sulfur hexafluoride, alkali metal diphenyl or dicyclohexyl phosphides are oxidized within seconds to tetraphenyl or tetracyclohexyl diphosphines. When bulky di-tert-butylphosphide is employed, fluorophosphine intermediates are detected. This is the first reported reaction of sulfur hexafluoride with metal phosphides, and a rare example of reactivity of sulfur hexafluoride at ambient temperature. This journal is

Synthetic route to vanadium(III) dichalcogenidophosphinate complexes, V(S2PPh2)3 and V(Se2PPh2)3: A spectroscopic and structural comparative study with analogous complexes of chromium(III), Cr(E2PPh2)3 (E=S, Se)

Addition of the potassium dichalcogenidodiphenylphosphinate salts, KE2PPh2 (E=S, Se), to either the THF solvate of vanadium(III) chloride or unsolvated chromium(III) chloride results in rapid ligand substitution and the formation of a series of closely-related trivalent, neutral mononuclear complexes, M(E2PPh2)3 (M=V, Cr; E=S, Se), isolated in modest to good yield. The metal dichalcogenidophosphinate complexes reported herein were characterized by IR, UV-vis, and 1H NMR spectroscopies, and their solid-state molecular structures were determined by single-crystal X-ray crystallography. Importantly, the comparative analysis includes the structural and spectroscopic studies of two rare V(III) dithio- and diseleno-phosphinate VE6 cores, as well as, two previously known CrE6 analogues. In the solid-state the title complexes exhibit trigonal distortion from octahedral with torsion angles ranging from 43(2) to 50.3(6)° and structural parameters consistent with ligation of progressively ‘softer’ chalcogen-donors.

Coordination chemistry of 2,2′-biphenylenedithiophosphinate and diphenyldithiophosphinate with U, Np, and Pu

New members of the dithiophosphinic acid family of potential actinide extractants were prepared: heterocyclic 2,2′-biphenylenedithiophosphinic acids of stoichiometry HS2P(R2C12H6) (R = H or tBu). The time- and atom-efficient syntheses afforded multigram quantities of pure HS2P(R2C12H6) in reasonable yields (～60%). These compounds differed from other diaryldithiophosphinic acid extractants in that the two aryl groups were connected to one another at the ortho positions to form a 5-membered dibenzophosphole ring. These 2,2′-biphenylenedithiophosphinic acids were readily deprotonated to form S2P(R2C12H6)1- anions, which were crystallized as salts with tetraphenylpnictonium cations (ZPh41+; Z = P or As). Coordination chemistry between [S2P(tBu2C12H6)]1- and [S2P(C6H5)2]1- with U, Np, and Pu was comparatively investigated. The results showed that dithiophosphinate complexes of UIV and NpIV were redox stable relative to those of UIII, whereas reactions involving PuIV gave intractable material. For instance, reactions involving UIV and NpIV generated An[S2P(tBu2C12H6)]4 and An[S2P(C6H5)2]4 whereas reactions between PuIV and [S2P(C6H5)2]1- generated a mixture of products from which we postulated a transient PuIII species based on UV-Vis spectroscopy. However, the trivalent Pu[S2P(C6H5)2]3(NC5H5)2 compound is stable and could be isolated from reactions between [S2P(C6H5)2]1- and the trivalent PuI3(NC5H5)4 starting material. Attempts to synthesize analogous trivalent compounds with UIII provided the tetravalent U[S2P(C6H5)2]4 oxidation product.

Preparation and Some Reactions of Thioacyl Diphenylthiophosphinoyl and Thioacyl Diphenylphosphino Sulfides

The reaction of sodium or caesium dithiocarboxylates with diphenylthiophosphinic and diphenylselenophosphinic chlorides gives purple thioacyl diphenylthiophosphinoyl 5 and dark green thioacyl diphenylselenophosphinoyl sulfides 6, which are useful thioacylating reagents under mild reaction conditions.Thioacyl diphenylphosphino sulfides 22, which can be obtained by the similar method using diphenylphosphinous chlorides, react with methanol to yield the corresponding methyl dithiocarboxylates 15, while the reactions of 22 with N-chlorosuccinimide lead to hitherto unknown N-(thioacetylthio)succinimides 28.
