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
容易获得Vaska型氟络合物反式[[Ir(F)(CO)(PR 3)2 ] [ 6:R = Et,7:R = Ph,8:R = i Pr,9:R = Cy ,10:R =吨卜]通过卤化物交换在实现反式-的[Ir(Cl)的(CO)(PR 3)2 ](1 - 5)与我4 NF。此外,复杂的反应6用SF 4,得到顺式,反式-的[Ir(F)2(SF 3)(CO)(PET3)2 ](11),而8 - 10不反应。反应性研究表明,可以通过水解或氟化物萃取选择性地在硫原子上操纵11,从而产生顺式,反式-[Ir(F)2(SOF)(CO)(PEt 3)2 ](12)和顺式,反式- [Ir(F)2(SF 2)(CO)(PEt 3)2 ] [AsF 6 ](13)。
