Reduction of secondary and tertiary phosphine oxides to phosphines

Chemical Society Reviews, 2015
Achiral or chiral phosphines are widely used in two main domains: ligands in organometallic catalysis and organocatalysis. For this reason, the obtention of optically pure phosphine has always been challenging in the development of asymmetric catalysis ...

Trends in the Usage of Bidentate Phosphines as Ligands in Nickel Catalysis

Chemical Reviews, 2020
A critically important process in catalysis is the formation of an active catalyst from the combination of a metal precursor and a ligand, as the efficacy of this reaction governs the amount of active catalyst.

Amino Acid-Derived Bifunctional Phosphines for Enantioselective Transformations

Accounts of Chemical Research, 2016
Even though seminal reports on phosphine catalysis appeared in the 1960s, in the last few decades of the past century trivalent phosphines were viewed primarily as useful ligands for transition-metal-mediated processes.

Nucleophilic Activation of Sulfur Hexafluoride: Metal‐Free, Selective Degradation by Phosphines

Angewandte Chemie - International Edition, 2018
The development of new methods for the chemical activation of the extremely inert greenhouse gas sulfur hexafluoride (SF6 ) not only is of current environmental interest, but also offers new opportunities for applications of SF6 as a reagent in organic ...
