Application
The electron-rich and sterically demanding trYPhos™ ligand has been used in the gold(I)-catalyzed hydroamination of acetylene, and has shown to be effective in a range of Buchwald-Hartwig amination reactions. The strong electron-donor strength and sterically demanding nature of the ligand has been shown to increase the rate of formation of the catalytically active mono-phosphine palladium species, often leading to decreased reaction times or allowing the use of lower reaction temperatures. trYPhos™ is the most strongest donor of the available YPhos™ligands and has been found to be effective alpha-arylation of aliphatic cyclic ketones.

Features and Benefits
Advantages of the trYPhos™ ligand over less electron rich ligand sources include, increased substrate scope in Buchwald-Hartwig amination reactions, including aryl chlorides, the use of more mild reaction conditions and improved activity in in C-N and C-C cross coupling reactions. The increased electron donor stregth of trYPhos™ has been shown to be effective in the challenging alpha-arylation of aliphatic ketones.
General description
trYPhos™ is an ylide-functionalized phosphine ligand developed in the lab of Prof. V. Gessner with demonstrated uses in Pd-catalyzed cross coupling reactions, including the arylation of ketones and arylation of amines. trYPhos™is the strongest donor of the available YPhos™ ligands, and is suited towards the most challenging alpha-arylation reactions.

Ylide-functionalized phosphines (YPhos) have recently proven to be strongly donating ligands that enable high catalyst activities in gold(I)-mediated transformations. We now report on a calorimetric study dealing with the [Au(YPhos)Cl] system and assess YPhos-Au bond dissociation enthalpies (BDE). Comparison with
