Intramolecular Phosphine−Phosphine Donor−Acceptor Complexes

Inorganic Chemistry, 2009
The reaction of 5-diphenoxyphosphanyl-6-diisopropylphosphinoacenaphthene 12 with chlorotrimethylsilane unexpectedly gave a phosphonium-phosphine compound 13, containing the structural motif of four phosphorus atoms connected in a chain. To explain the mechanism of this complex transformation, a proposed intermediate 5-dichlorophosphino-6 ...

Tertiary Amine-Mediated Reductions of Phosphine Oxides to Phosphines

Organic Letters, 2023
The 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

Enantioselective Phosphine Organocatalysis

Synlett, 2009
The broad potential synthetic usefulness of phosphine-promoted reactions has stimulated many recent investigations on enantioselective variants of known reactions of this family, as well as the search for new, specifically designed, chiral phosphorus catalysts.

Reduction of phosphine oxides to phosphines

Tetrahedron Letters, 2019
Abstract The digest is devoted to the most widespread reducing agents which are used for the reduction of tertiary and secondary phosphine oxides, phospholene oxides, phospholane oxides, phosphonates, phosphinates, α- and β-hydroxy and thiomethyl phosphine oxides, α-aminophosphine oxides. Stereoselectivity of reactions is described.

Phosphine-Stabilized Digermavinylidene

Journal of the American Chemical Society, 2019
An intramolecular germylene-phosphine Lewis pair (1) was reacted with germanium dichloride to give in 92% yield a phosphine adduct of a chloro substituted germyl-germylene (2). After reduction of this dichloride with strong reductants like the Mg(I) reagent {(MesNacnac)Mg}2 (72% yield) or Na (52% yield) a phosphine stabilized digermavinylidene (3) was ...
