Suzuki Cross-Coupling of [2.2]Paracyclophane Trifluoroborates with Pyridyl and Pyrimidyl Building Blocks

Abstract

We report a new Suzuki cross-coupling protocol for high yielding derivatization of [2.2]paracyclophane with pyridyl and pyrimidyl substituents. The [2.2]paracyclophane trifluoroborate salt presented herein is a bench stable, easily accessible, and convenient substitute to former cross-coupling substrates. This will be of very high interest for future paracyclophane derivatization endeavors.
