Chelation kinetics of bidentate phosphine ligands on pentacoordinate ruthenium carbonyl complexes

Chelation kinetics of the complexes Ru(CO)4(η1-(P-P)) have been studied in heptane, where P-P = Ph2P(CH2)nPPh2 (n = 1, 2, 3, or 4, i.e., dppm, dppe, dppp, or dppb), Ph2P(NMe)PPh2 (dppma), Ph2P(o-C6H4)PPh2 (dpp-benzene), or R2P(CH2)2PR2 (R = Me or Cy, i.e., dmpe or dcpe). The complexes were prepared in situ by reaction of the bidentate ligands with Ru(CO)4(C2H4), which itself was prepared in situ by photolysis of Ru3(CO)12 under C2H4. The initially formed Ru(CO)4(η1-(P-P)) complexes react cleanly to form axial-equatorial Ru(CO)3(η2-(P-P)), as shown by the crystallographic structures of the products when P-P = dppe, dmpe, and dpp-benzene and the close similarity of their FTIR spectra to those of the other products. The chelated products undergo further reaction in solution or the solid state, and the product when P-P = dppma has been characterized by crystallography as Ru2-(CO)3(μ-PPh2)(μ-Ph2PNMePPh2). The kinetics of the displacement of CO from Ru(CO)4(η1-(P-P)) in n-heptane are characterized by ΔH? values that are lower by up to 9 kcal mol-1 than those of their monodentate P-donor analogues. ΔS? values range from quite positive to slightly negative and suggest a trend from purely dissociative to appreciably associative mechanisms along the series P-P = dpp-benzene 4L complexes when L = monodentate P-donor ligands.

The Generation and Reactivity of Versatile Ruthenium Carbonyl Organometallic Intermediates by Cluster Photochemistry

The use of inorganic cluster photochemistry in the synthesis of both mononuclear and higher-nuclearity compounds is discussed.Owing to its selectivity, cluster photochemistry offers a high-yield route to both known and novel target compounds by the selective labilisation of ligands and cleavage of metal-metal bonds.Attention is focused on the trinuclear cluster , looking mechanistically at both photofragmentation and photosubstitution processes and at the synthetic potential of the reactive intermediates formed.The role of cluster photochemistry in catalysis and in the elucidation of the mechanism for a number of catalytic processes is also discussed.
