Phosphines sulfur donor ligands

Miscellaneous Methods of Preparing Phosphines. Approaches to the synthesis of specific types of organophosphine have been reviewed, covering phosphinoaryloxazolines, /ra j-2,5-disubstituted phospholanes, " new chiral phosphines which have been reported since 1990, chiral hydroxyphos-phines, and phosphorus-sulfur donor ligands.The uses of phosphine (PH3) in the synthesis of organophosphines has also been reviewed. A direct route for the synthesis of arylphosphines is offered by the reaction of...

Calorimetric measurements in solution support these observations A relative enthalpy scale for different NHCs coordinated to ruthenium(II) [Eq. (40)] shows that NHCs have a higher donor capability than the best phosphine donor ligands. The only exception is the sterically extremely demanding l,3-di(l-adamantyl)imida-zolin-2-ylidene (Table III). The enthalpies for the formation of sulfur adducts...
