Abstract: Reactions between Ru3(CO)12 and 1,8- bis(diphenylphosphino)naphthalene (dppn) have given the four complexes Ru 3(μ-H){μ3-PPh2(nap)PPh(C 6H4)}(CO)8 (1), Ru4(μ-H) {μ3-PPh2(nap)PPh(C6H4)}(μ-CO) 3(CO)7 (2) and Ru4(μ-H)(μ3- C6H4){μ-PPh(nap)PPh2}(CO)11 (3) (in refluxing thf), and Ru4{μ4-P(nap)PPh 2}(μ4-C6H4)(μ-CO)(CO) 9 (4) (in refluxing toluene) which have been characterised by single crystal X-ray studies. They have been formed by aryl C-H and aryl C-P bond cleavage reactions, presumably from an initial (unobserved) chelate dppn complex. The unchanged chelating ligand is found in Ru3(μ-dppm) (CO)8(dppn) (5), obtained from Ru3(μ-dppm)(CO) 10 and dppn in refluxing thf. © 2004 Elsevier B.V. All rights reserved.
