Sulfonated Phosphine‐Palladium/Bisguanidinium Ion Pair Catalyzed Enantioselective Allylic Amination
Comprehensive Summary In this study, we successfully developed ion pair catalysts consisting of chiral bisguanidinium (BG) cations and non‐chiral sulphonated phosphine‐palladium complexes as counterions. These ion pairs catalyzed allylic alkylation reactions with excellent enantioselectivities. Furthermore, these reactions can be easily performed on a gram‐scale, demonstrating their potential for industrial applications. We were able to obtain 1 H NMR of the ion pair catalyst and identified the 31 P NMR of the sulphonated phosphine‐palladium complex.
