Abstract

Thermolysis of [Ru-3(CO)(10)(Ph2PC=CBut)(2)] (1a) gives the 48-e cluster [Ru-3(mu-eta(1),eta(2)-C=CBut)(2)(mu-PPh2)(2)(CO)(6)] (4), which readily adds CO or PPh3 to give the corresponding 50-e clusters [Ru-3(mu-eta(1),eta(2)-C=CBut)(2)(mu-PPh2)(2)(CO)(6)(L)] (L = CO, 5a, PPh3, 6) while thermolysis of [Ru-3(CO)(10)(Ph2PC=CPh)(Ph2PC=CR)] (R = Ph, 1b; Bu-t 1c) affords 50-e [Ru-3(mu-PPh2)(mu-eta(1)-eta(2)-C=CPh)(mu-eta(1),eta(2)-C=CR)(CO)(7)] (5b, 5c) directly, which convert smoothly to the 48-e diyne clusters [Ru-3(mu-eta(2)-PhC2C=CR)(mu-PPh2)(2)(CO)(7)] (7b, 7c). In the case of [Ru-3(CO)(10)(Ph2PC=CPh)(2)] the compound {Ru-2[eta(1),eta(1) : eta(2),eta(2) -PhCC(PPh2)CCPh](CO)(5)}(mu-PPh2)[Ru(CO)(3)] (8) is also obtained.
