Reinvestigation of Aminomethyltrifluoroborates and Their Application in Suzuki−Miyaura Cross-Coupling Reactions
摘要:
A reinvestigation into the chemical composition of potassium aminomethyltrifluoroborates is reported. These trifluoroborato salts have been reassigned as zwitterionic ammoniomethyltrifluoroborates. Minor adjustments to the previously disclosed reaction conditions are reported that permit a similar level of activity as nucleophiles in Suzuki-Miyaura cross-coupling reactions.

previously reported the Suzuki−Miyaura reaction of N,N-dialkylaminomethyltrifluoroborates with arylbromides. Herein, we report a further investigation of the scope and limitations of this palladium-catalyzed aminomethylation reaction. Aryl chlorides, iodides, and triflates coupled in good to excellent yields to give N,N-dialkylbenzylic amines. The aminomethylation of alkenyl bromides was also examined.
