Reactivity of Xantphos-Type Rhodium Complexes Towards SF₄ : SF₃ Versus SF₂ Complex Generation.

ABSTRACT: S-F-bond activation of sulfur tetrafluoride at [Rh(Cl)(^tBu xanPOP)] (1; ^tBu xanPOP=9,9-dimethyl-4,5-bis-(di-tert-butylphosphino)-xanthene) led to the formation of the cationic complex [Rh(F)(Cl)(SF₂ )(^tBu xanPOP)][SF₅ ] (2 a) together with trans-[Rh(Cl)(F)₂ (^tBu xanPOP)] (3) and cis-[Rh(Cl)₂ (F)(^tBu xanPOP)] (4) which both could also be obtained by the reaction of SF₅ Cl with 1. In contrast to that, the conversion of SF₄ at the methyl complex [Rh(Me)(^tBu xanPOP)] (5) gave the isolable and room-temperature stable cationic λ⁴ -trifluorosulfanyl complex [Rh(Me)(SF₃ )(^tBu xanPOP)][SF₅ ] (6).
