摘要：

Three-component cyclization reactions between ethene or 1,3-butadiene, CO, and the C2PPh2 ligand present in Ru5(mu-5-C2PPh2)(mu-PPh2)(CO)13 have given the complexes Ru4{mu-4-sigma(O,P),sigma,eta(2)-C5H4(O)(PPh2)}-(mu-PPh2)(CO)11 (2) and Ru4{mu-4-sigma(O,P),sigma,eta(2)-C6H3(CO)(PPh2)}(mu-PPh2)(CO)9(eta(3)-C4H7) (3), respectively. X-ray crystallographic studies showed that these complexes contain metalated diphenylphosphinocyclopentenone and -benzoyl ligands, respectively. Crystals of 2 are orthorhombic, space group P2(1)2(1)2(1), Z = 4, a = 19.512 (15) angstrom, b = 18.700 (11) angstrom, c = 11.048 (4) angstrom, V = 4031 angstrom3, R = 0.036, R(w) = 0.036, based on 4465 reflections with I > 3-sigma-(I). Crystals of 3 are triclinic, space group P1BAR, Z = 2, a = 17.800 (2) angstrom, b = 11.502 (5) angstrom, c = 11.283 (2) angstrom, alpha = 93.83 (2)-degrees, beta = 91.65 (1)-degrees, gamma = 99.30 (2)-degrees, V = 2273 angstrom3, R = 0.037, R(w) = 0.048, based on 7097 reflections with I > 3-sigma-(I).
