| Abstract: | 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. |
