The fluoro analogue of Wilkinson's catalyst, [(Ph3P)3RhF] (1), was synthesized and fully characterized. Both solution behavior and solid-state geometry parameters of1were found to be surprisingly similar to those of Wilkinson's catalyst. Unlike Wilkinson's catalyst however,1exhibited most unusual reactivity toward the notoriously inert C−Cl bond of nonactivated chloroarenes. The novel Ph−Cl activation with1includes fluorine transfer from the metal to a phosphine ligand and evidently phenyl transfer from the phosphine to Rh to produce an electron-rich σ-phenylrhodium intermediate.
