affect the isomer distribution between tail-product (I) and head-product (II). The choice of ligands had the greater influence, where RhI-based catalysts with the strong electron withdrawing ligand CO favoured production of isomer II, while RhI catalysts with strong electron donating ligands (for example triarylphosphines) gave isomer I as the main product. In contrast to the square planar carbonyl complex
