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

This chapter gives an account of the newer developments on the synthesis and reactivity of phosphine chalcogenides, mainly oxides and sulfides. A series of new synthetic methods for phosphine oxides is discussed, followed by preparations utilizing simple P-reagents such as P(iii)- and P(v)-chlorides, and >P(O)H species.

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

Microemulsions with Alkyldimethyl Phosphine Oxides and Alkyldiethyl Phosphine Oxides
Langmuir, 2008Alkyldimethyl phosphine oxides (C n DMPO) as well as alkyldiethyl phosphine oxides (C n DEPO) with chain lengths of n = 10 (decyl), 12 (dodecyl), and 14 (tetradecyl) were synthesized and purified to study how the formation of microemulsions depends on the size of the headgroup and on the length of the alkyl chain.

Reduction of phosphine oxides to phosphines with the InBr3/TMDS system
Tetrahedron, 2012An efficient method for the reduction of phosphine oxide derivatives into their corresponding phosphines is described. The system InBr3/TMDS allows the reduction of different secondary and tertiary phosphine oxides as well as aliphatic and aromatic phosphine oxides.

Coordination chemistry with phosphine and phosphine oxide-substituted hydroxyferrocenes
Dalton Transactions, 2010New unsymmetrical hydroxyferrocenes were synthesised from dibromoferrocene. The oxygen heteroatom was introduced via lithiation and quenching with bis-trimethylsilylperoxide followed by hydrolysis to unmask the hydroxyl functionality. The coordination chemistry of 1'-(diphenylphosphino)-1-hydroxyferrocene 2 was explored with palladium and rhodium ...

From phosphine-promoted to phosphine-catalyzed reactions by in situ phosphine oxide reduction
Tetrahedron Letters, 2016Abstract The well-known stoichiometric phosphine-promoted reactions such as the Wittig, Mitsunobu, Staudinger, Appel reactions, and others are widely used in organic chemistry. Recently, many efforts have been made to render these reactions catalytic in phosphine.
