一般描述

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.

应用

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.

特点和优势

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.
