Mi. Bruce et al., UNUSUAL COUPLING OF DIYNES AND CO ON AN RU-3-CLUSTER - CRYSTAL-STRUCTURE OF (O)C(SIME3)C(C-CSIME3)CCPH)(MU-DPPM)(MU-CO)(CO)(6), Russian chemical bulletin, 47(5), 1998, pp. 983-987
Among several products isolated in the reaction between Ru-3(mu(3)-PhC
2C=CPh)(mu-dppm) (CO)(8) and Me3SiC=CC=CSiMe3 was the )-CPhCC(O)C(SiMe
3)C(C=CSiMe3)CCPh}(mu-dppm)(CO)(7) complex formally obtained by coupli
ng of the two diynes and a CO molecule on the Ru-3 framework. Other pr
oducts were Ru-4(mu(4)-PhC2C=CPh)(mu-dppm)(CO)(10) and the already kno
wn complex Ru-3{mu(3)-PhCCHCC(C6H4)}(mu-dppm)(CO)(8).
