Bis-phosphanated compounds are regarded as the most ubiquitous privileged ligand structures in transition-metal catalysis. The development of highly atom economical reactions is of great importance for their syntheses because less atom economical methods often require complicated purification procedures under inert atmospheres to remove excess starting materials and byproducts. Herein, the photoinduced addition reactions of diphosphane monosulfides bearing PV(S)?PIII single bonds to alkenes is disclosed. These reactions require only equimolar amounts of the diphosphane monosulfide relative to the alkene and facilitate highly selective introduction of two different types of phosphorus-containing groups, such as thiophosphoryl and phosphanyl groups, into a variety of alkenes without any catalyst, base, or additive.
SYNTHESIS OF SOME FUNCTIONALIZED PHOSPHINOCARBOXYLIC ACIDS

Various functionalized phosphinocarboxylic acids have been prepared by a number of complementary methods.Reactions of relatively electron-poor secondary phosphides with electron-rich halocarboxylates in liquid ammonia give high yields of phosphinocarboxylates.The substitution reactionmay proceed by a classical SN2 mechanism or by an SN rad mechanism.Reduction of the carboxilate can be a deleterious side reaction in the preparation of phosphinoacetic acids.Several phosphinopropionic acids are prepared by the Michael adition of diphenylphosphine to unsaturated esters.A valuable method proved to be the reaction of dichlorophosphinoacetic ester with functionalized organometallic reagents. Key words: Phosphine; carboxylic acid; ligand; functionalized; synthesis; NMR data.
ELECTROCHEMICAL SYNTHESIS OF TERTIARY PHOSPHINES FROM ORGANIC HALIDES AND CHLOROPHOSPHINES
Folest, J. C.,Nedelec, J. Y.,Perichon, J.
, p. 1885 - 1886 (2007/10/02)
The electrochemical synthesis of a wide range of tertiary mono- and diphosphines has been achieved in very simple and mild conditions, in an undivided electrolytic cell with a sacrificial anode of magnesium.
