Iridium. Iridium analogues of catalytically active rhodium complexes are frequently too stable to function as catalysts, as has been illustrated by the preparation of the iridium model compounds mentioned in the previous paragraph. The mechanism of hydrolytic degradation of fluoro-olefin complexes has been discussed. ... 

Darses and co-workers have published a series of papers on the synthesis of stereo-defined trisubstituted alkenes by the coupling of readily available unreactive MBH adducts with either organoboronic acids or potassium tri-fluoro(organo)borates in the presence of a rhodium complex via a reaction pathway involving a 1,4-addition/p-hydroxy elimination mechanism. Compared with the aforementioned Pd-catalyzed cross-coupling reaction, this reaction does not need the activation of the hydroxyl group with acetate or carbonate therefore it is more desirable, particularly in terms of atom economy. For the MBH adducts derived from methyl acrylates, the initial reported catalyst, [ Rh-(cod)Cl 2], was active at 50 °C for boronic acids and at 70 °C... 

Diazoalkanes were readily decomposed and underwent [2+l]-type cycloaddition to alkenes in the presence of catalytic amounts of rhodium complexes. Rh2(OAc)4 is the simplest complex for the reaction. For example, fluoro-cyclopropane 134 was prepared by the carbene addition to fluoroalkene 133 (Scheme 1.64) [108]. A copper catalyst also catalyzed the addition reaction. 

Parameters for a range of fluoro-olefin complexes of rhodium and iridium are given in Tables XI (97) and XII. The vinyl fluoride complex...
