Abstract
The preparation of trinuclear ruthenium complexes of the type Ru3(CO)12 –nLn(L = tertiary phosphine or arsine; n= 1–4) is described. Their i.r. and 1H n.m.r. spectra are discussed and possible structures suggested. The complexes Ru3(CO)9L3[L = PPh3, P(m-C6H4Me)3, P(p-C6H4Me)3 or PMePh2] undergo controlled pyrolytic reactions in boiling decalin, affording complexes of the type Ru2(CO)6(PAr2)2(Ar = Ph or m-MeC6H4),Ru2(CO)6[PPhR(C6H4)](PPhR)(R = Ph or Me), Ru2(CO)6[PPh2(C6H4)]2, and Ru3(CO)7(PAr3)(PAr2)(Ar = Ph, m-MeC6H4, or p-MeC6H4). Spectroscopic data suggest structures containing bridging phosphido-ligands, and ortho-metallated phenyl rings.Keywords
