General description
joYPhos™ 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.
Application
The electron-rich and sterically demanding joYPhos™ ligand has been used in the gold(I)-catalyzed hydroamination of acetylene,citation 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.

Features and Benefits
Advantages of the joYPhos™ 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.
