摘要
Reactions Of Os-3(CO)(12) with 1,8-bis(diphenylphosphino)naphthalene (dppn) are described. Crystallo graphically characterised complexes isolated from a reaction carried out in refluxing toluene are OS3(mu-H)(2) {mu-PPh2(nap)PPh(C6H4)}(2)(CO)(6) (1), Os-3(mu-H){mu(3)-PPh2(nap)PPh(C6H4)}(CO)(8) (2) and Os-2(mu-PPh2) {mu-PPh2) {mu-PPh2(nap)}(CO)(5) (3) (nap = 1,8-C-10-H-6), while at r.t. in the presence of ONMe3, only Os-3(CO)(11) {PPh2(1-C10H7)} (4) was isolated. While 1 and 2 contain ligands formed by metallation of a Ph group of dppn, as found also in complexes obtained from dppn and Ru-3(CO)(12), ligands in 3 and 4 are formed by cleavage of a P-nap bond, not found in the Ru series.
