Rhodium diphosphine systems, including chiral ones, were used as catalyst precursors for the hydroformylation of 2,5-dihydrofuran. The effect of the reaction conditions and the bite angle on the activity and selectivity of the reaction were studied. The s

Complexes of general formula 1-5 and i-p)Ru(μ-pz)(μ-Cl)2Rh(cod)> 7 were prepared starting from mononuclear acetylacetonate and pyrazole or pyrazolate-containing moieties.Complexes 1-5 react with CO yielding derivatives 8-12.Complexes 13 and i-p)ClRu(μ-pz)2Ir(CO)2> 12 react with NaX to give (X = I; 14; or N3, 15) and i-p)Ru(μ-pz)2IrX(CO)2> (X = Br, 16; or I, 17.The dicarbonyl compound 10 and i-p)ClRu(μ-pz)2M'(CO)2> (M' = Rh, 11; or Ir, 12) react with diphosphines (L-L) or 1,2-bis(diphenylarsino)ethane (dpae) and NaBPh4 or AgBF4 affording cationic complexes >A 23-31 A = BPh4 or BF4 (not all possible combinations)>.In this reaction intermediates >A have been isolated in some cases.The crystal structure of one of these BPh4*0.5MeOH 19 has been determined by X-ray diffraction methods.Crystals are monoclinic, space group P21/c, a = 15.996(2), b = 22.199(4), c = 18.874(3) Angstroem, β = 115.04(1) deg and Z = 4.The complex cation consists of two iridium atoms bridged by two pyrazolates and one ketonic carbonyl group.An η5-C5Me5 ligand, a chelate dppen and a terminal CO group complete the co-ordination spheres of the iridium atoms, which are separated by 3.440(5) Angstroem.
