C–F bond activation of perfluorinated arenes by a bioxazoline-derived N-heterocyclic carbene. Issue 4 (22nd December 2016) - Emerson-King, Jack
Abstract : IBioxMe4 enacts selective single and double C–F bond activation of octafluorotoluene and hexafluorobenzene, respectively. Abstract : The N-heterocyclic carbene IBioxMe4 enacts selective single and double C–F bond activation of octafluorotoluene and hexafluorobenzene, respectively. The formation of the fluoroarene substituted, zwitterionic imidazoliumolate products is consistent with a mechanism involving nucleophilic aromatic substitution and subsequent oxazoline ring opening by liberated fluoride.
