The tetrahedral cluster [RuCo(3)(CO)(12)](-) reacts with various alkynes, including the new PhCtbd1;CC(O)NHCH(2)Ctbd1;CH (L(1)()), to afford the butterfly clusters [RuCo(3)(CO)(10)(micro(4)-eta(2)-RC(2)R')](-) (1, R = R' = C(O)OMe; 2, R = H, R' = Ph; 3, R = H, R' = MeC=CH(2); 4, R = H, R' = CH(2)OCH(2)Ctbd1;CH; 5, R = H, R' = CH(2)NHC(O)Ctbd1;CPh), in which the ruthenium atom occupies a hinge position
四面体簇[RuCo(3)(CO)(12)](-)与各种炔烃反应,包括新的PhCtbd1; CC(O)NHCH(2)Ctbd1; CH(L(1)()),得到蝴蝶簇[RuCo(3)(CO)(10)(micro(4)-eta(2)-RC(2)R')](-)(1,R = R'= C(O)OMe; 2,R = H,R'= Ph; 3,R = H,R'= MeC = CH(2); 4,R = H,R'= CH(2)OCH(2)Ctbd1; CH; 5, R = H,R'= CH(2)NHC(O)Ctbd1; CPh),其中钌原子占据铰链位置,炔烃以micro(4)-eta(2)方式配位。阴离子1-3与[Cu(NCMe)(4)] BF(4)的反应导致12e片段Co(CO)(-)选择性丢失,形成[RuCo(2)(CO)(9)( micro(3)-eta(2)-RC(2)R')]](6,R = R'= C(O)OMe;
