Using the mixed phosphine-stibine compound [IrCl(C2H4)(PiPr(3))(SbiPr(3))] (2) as the starting material, the square-planar carbeneiridium(I) complexes [IrCl(=CR2),(PiPr(3))(SbiPr(3))] (3a,b) and trans-[IrCl(= CR2)(PiPr(3))(2)] (4a,b) were prepared. The cyclopentadienyl derivative [C5H5Ir(=CPh2)(PiPr(3))] (5), obtained from 3a and NaC5H5, reacts with HCl by attach of the Ir=CPh2 bond; in, contrast, upon treatment of 4a with HCl or HBF4, hydridoiridium(lll) complexes 8 and 9 with art intact Ir=CPh2 unit are formed.
