Abstract

The chemistry of some ruthenium cluster carbonyls containing allenylidene ligands has been reinvestigated. Treatment of Ru3(μ-H){μ3-C2CAr2(OH)}(CO)9 [Ar = Ph 15, tol (tol = 4-MeC6H4)] with HBF4·OMe2 gave Ru3(μ-H)(μ3-CCCAr2)(CO)9 (Ar = Ph, R = H, Me; Ar = tol, R = H). Substitution of CO by PPh3 or dppm gave Ru3(μ-H)(μ3-CCCPh2)(μ-OH)(CO)7(L)2 (L = PPh3, L2 = dppm; from 15), while in the presence of HBF4, the hydroxy-free complexes Ru3(μ3-CCCAr2)(μ-dppm)(μ-CO)(CO)7 were obtained. Reactions of 15 with K[BHBus3], followed by HBF4 or AuCl(PPh3), also resulted in loss of water to give Ru3(μ-H)(μ-E)(μ3-CCCPh2)(CO)9 [E = H or Au(PPh3), respectively]. X-Ray structures of six of the complexes are reported.
