Reductive coupling of alkynes to give ruthenium and osmium clusters of thetype [M-3(1,3-diene)(mu(3)-X)(CO)(8)] containing mu-eta(2),eta(2)- or eta(4)-1,3-diene
S. Ali et al., Reductive coupling of alkynes to give ruthenium and osmium clusters of thetype [M-3(1,3-diene)(mu(3)-X)(CO)(8)] containing mu-eta(2),eta(2)- or eta(4)-1,3-diene, CHEM COMMUN, (24), 1999, pp. 2541-2542
Replacement of a CO ligand by MeCN in the capped clusters [M-3(mu-H)(2)(mu(
3)-X)(CO)(9)] (M = Ru, X = NSO2C6H4Me-4 or M = Os, X = S) allows reductive
coupling of alkynes (RC=CH, R = H or Ph) to give regioselectively the 1,3-d
iene clusters [M-3(C4H4R2)(mu(3)-X)(CO)(8)], with the diene mu-eta(2),eta(2
)-coordinated for ruthenium and eta(4) for osmium.
