Synthesis and Reactivity of Iridium(I) Fluorido Complexes: Oxidative Addition of SF4 at trans-[Ir(F)(CO)(PEt3)2]
The facile access to the Vaska type fluorido complexes trans-[Ir(F)(CO)(PR3)2] [6: R = Et, 7: R = Ph, 8: R = iPr, 9: R = Cy, 10: R = tBu] was achieved by halide exchange at trans-[Ir(Cl)(CO)(PR3)2] (1–5) with Me4NF. Furthermore, the reaction of complex 6 with SF4 gave cis,trans-[Ir(F)2(SF3)(CO)(PEt3)2] (11), whereas 8–10 did not react. Reactivity studies revealed that 11 can selectively be manipulated at the sulfur atom by hydrolysis or fluoride abstraction to give cis,trans-[Ir(F)2(SOF)(CO)(PEt3)2] (12) and cis,trans-[Ir(F)2(SF2)(CO)(PEt3)2][AsF6] (13), respectively.
