Abstract

Substitution reactions of M3(CO)12 (M = Fe, Ru) and Ru4((μ-H)4(CO)12 involving a range of ferrocenyl phosphines are described. Compounds isolated and characterized include Fe3(CO)11PFcPh2, Fe3(CO)10(PBuFcPh)2, Fe(CO)4L (L = PFc2Ph, PFc3), Ru3(CO)11L (L = PFc3, PFc2Ph, PFcPh2), Ru3(CO)10L2 (L = PFc2Ph, PFcPh2), and Ru(CO)4PFc3. Ru4((μ-H)4(CO)10 (L—L) and Ru3(CO)10(L—L) result from reactions with L—L = (Ph2PC5H4)2Fe. The structure of two derivatives are described. Crystals of Ru3(CO)11(PFcPh2) are triclinic, space group P-1, a = 8.576(1), b = 11.150(2), c = 9.160(3) Å, α = 76.65(1), β = 80.75(1), γ = 72.02(1)°, Z = 2, final RW = 0.027 from 3144 observed reflections. Ru3(CO)10(Ph2PC5H4)2Fc, monoclinic crystals, space group C 2/c, a = 17.005(2), b = 18.411(1), c = 14.961(1) Å, β = 117.112(8)°, Z = 4, final RW = 0.023 from 2395 observed reflections. Keywords: ferrocenylphosphines, ruthenium carbonyl derivatives, structures, synthesis, iron carbonyl derivatives.
