Synthesis and oxidation of phosphine cations
Dalton Trans., 2017Cationic phosphines of the form [(L)PPh2]+ are prepared from Ph2PCl and carbenes (L), including a chiral bis(oxazoline)-based carbene, a cyclic(alkyl)(amino) carbene, and a 1,2,3-triazolium-derived carbene. A related dication was prepared from PhPCl2 and a bis-carbene. The monocations, but not the dication, can be oxidized with XeF2.

Tris(pyrazolyl)phosphine Oxide and Tris(triazolyl)phosphine Oxide Scorpion Ligands
European Journal of Inorganic Chemistry, 2013AbstractDFT calculations were performed on copper(I) complexes of neutral scorpion ligands based on either pyrazolyl (Pz) or triazolyl (Tz) rings with both methane and phosphine oxide apexes, that is, HC(Pz)3, OP(Pz)3, HC(Tz)3, and OP(Tz)3. The analyses reveal that all four ligands have similar donor properties and that their differences are easily ...

Phosphine oxide surfactants revisited
Advances in Colloid and Interface Science, 2016This review summarizes everything we currently know about the nonionic surfactants alkyl dimethyl (C(n)DMPO) and alkyl diethyl (C(n)DEPO) phosphine oxide (PO surfactants). The review starts with the synthesis and the general properties (Section 2) of these compounds and continues with their interfacial properties (Section 3) such as surface tension ...

Tertiary Amine-Mediated Reductions of Phosphine Oxides to Phosphines
Organic Letters, 2023The reduction of phosphine oxides without the use of highly reactive reductants represents a safer and more sustainable solution for recycling of organophosphorus compounds. Herein, we disclose an N,N,N',N'-tetramethylethylenediamine (TMEDA)-mediated reduction via an unusual intermolecular hydride transfer. Mechanistic studies suggest that TMEDA serves

Mild Reduction of Phosphine Oxides with Phosphites To Access Phosphines
Angewandte Chemie International Edition, 2017AbstractA new method for the iodine‐catalyzed reduction of phosphine oxides with phosphites at room temperature is reported. The mild reaction conditions, scalability, and simple purification requirements render it a method of choice for the large‐scale production and facile regeneration of a variety of phosphines. Mechanistic studies, supported by DFT
