The reactions of butatrienylidene iridium complexes with CO depend strongly on the trans ligand. The trans chloro complex 11 reversibly adds CO to form a five-coordinate butatrienylidene complex 31 whereas the trans azido complex yields with CO an alkenyl(azido)ethynyl complex (32) and the trans methyl complex the alky-nylalkenyl complex 33 (Scheme 3.31) [3].

The present preparative procedure for perchlorato complexes of rhodium and iridium appears to be of general utility for the synthesis of perchlorato complexes of transition metals. The assignment of trans planar structures for [M(OC103)(CO)(Ph3P)2] (M = Ir, Rh) is based on the vibrational and electronic spectral similarities between the perchlorato complexes and their well-known chloro precursors, tims-[MCl(CO)(Ph3P)2].5,6...

Hydrosilylation of phenylacetylene with triethylsilane catalysed by rm -chloro(car-bonyl)bis(triphenylphosphine)iridium yields the trans-2idduct 111, accompanied by traces of the cis-isomQT 278 and of the regioisomer 219. ... 

Jenkins and Shaw (77) have shown that metal-chlorine stretching frequencies in the far-infrared spectra of octahedral complexes are primarily dependent on the nature of the ligand trans to the chlorine. The configurations of a number of adducts derived from (IV) were determined using this technique (41). For example, addition of bromine or iodine to the chloro complex (IV) afforded octahedral complexes (V), apparently by trans addition. Inasmuch as chlorine attacks iridium-bromine or iridium-iodine bonds it was not possible to carry out this reaction by reversing the role of the halogens. It is uncertain whether the configurations of the adducts (V) resulted from thermodynamic or kinetic control.
