| dc.description | Rhodium coordination complexes or systems formed with rhodium in the presence of ligands, in particular phosphorus derivatives, have been extensively and successfully used as catalytic precursors in homogeneous catalysis for many years. The particular properties of both oxidation states of Rh(I) and Rh(III) allow for the successive oxidative addition, insertion, reductive elimination steps, and facilitate the activity and efficiency of the rhodium catalysts. The selectivity can be controlled and modified due to the versatility and modification possibilities of the ligands coordinated to the rhodium center. After the breakthrough of the application of RhCl(PPh3)3 as a hydrogenation catalyst, rhodium catalysis blossomed enormously and cationic rhodium(I) phosphorus systems were also applied in hydrogenation reactions, being particularly attractive due to the use of chiral ligands allowing for the enantioselective hydrogenation reaction of prochiral substrates. The main characteristic of catalytic rhodium systems is the high selectivity and enantioselectivity achieved in most of the homogeneous catalytic processes. A relevant example is the hydroformylation reaction which involves a one-carbon chain elongation by the addition of carbon monoxide and hydrogen across a C=C double bond. It is well known that this is one of the main industrial processes carried out by homogeneous catalysis concerning the formation of aldehydes from alkenes. The use of the appropriate ligands allows the control of the regioselectivity and more recently the control of the enantioselectivity. | en |
