ChemInform Abstract: Room-Temperature Palladium-Catalyzed Cross-Coupling of Aryltrimethylammonium Triflates with Aryl Grignard Reagents.
Aryltrimethylammonium triflates and tetrafluoroborates were found to be highly reactive electrophiles in the Pd-catalyzed cross coupling with aryl Grignard reagents. The coupling reactions proceed at ambient temperature with a nearly stoichiometric quantity of Grignard reagent, and diverse functionality is tolerated. Competition experiments established the reactivity of PhNMe(3)OTf relative to PhCl, PhBr, PhI, and PhOTf.
