The synthesis and catalytic activity of novel phosphine palladium PEPPSI and dimer complexes bearing RuPhos, SPhos and XPhos phosphines is reported.
Selective enhancement of the oxo-palladium transmetalation pathway in Ag+-mediated Suzuki–Miyaura catalyst transfer polymerization enables direct participation of N-methyliminodiacetic acid (MIDA) boronates in the polymerization process.
An easily made vinyl-functionalized amphiphilic polymer, PEG-PVEG designed on the basis of metal–olefin interactions, has been developed and applied to aqueous Suzuki–Miyaura coupling via a micellar palladium catalyst in extremely high efficiency.
A novel palladium-catalyzed carboetherification reaction of β,γ-unsaturated ketoxime with gem-dihaloolefin has been developed. This process offers an efficient route for the assembly of isoxazoline bis-heterocycles in moderate to good yields.
Application of aryl triflates and terminal acetylenic enamines as surrogates of unactivated ketones enables an unprecedented Pd-catalyzed 5-exo-dig cyclization/cross coupling sequence.
