Abstract

The addition of the catalyst (FeCp(CO)₂)₂ to the solution reactions of Ru4(μ-H)4(co)1₂ with L (L = P(OEt)₃, PPh₃, AsPh₃) affords the substitution derivatives Ru₄(μ-H)₄(CO)_12-xL_x(x = 1–4, L = P(OEt)₃, PPh₃; x = 1, 2, L = AsPh₃) with good selectivity modulated by the carbonyl to ligand ratio and in satisfactory yield. Multinuclear variable temperature NMR studies at different temperatures show that the tri- and tetrasubstituted products are each obtained in only one isomeric form while for L = P(OEt)₃ the monosubstituted derivative exists as two isomers in solution. The disubstituted derivatives form only one isomer for L = P(OEt)₃, whereas two isomers are observed for L = PPh₃, AsPh₃. The stereochemical nonrigidity of the title compounds has been investigated, and correlations between solid-state and solution structures are discussed.
