Abstract

We report a fluorine transfer reaction in which fluorine from a perfluorinated ligand undergoes C-F bond activation and transfer to an electrophile, resulting in the formation of a new fluorinated product and dimerization of the mono-defluorinated complex. Treatment of [(η5,κ2C-C5Me4CH2C6F5CH2NC3H2NMe)- RhCl] with the organic electrophile, toluoyl chloride, resulted in the formation of a rhodium (III) metallocycle via C-F bond activation assisted defluorinative coupling. Fission of the C-F bond liberated nucleophilic fluoride, which converted acyl chloride to acyl fluoride. The overall reaction was monitored using a multivariant analysis approach in real time.
