Dismantling a dinuclear metallacyclopentadiene: alkyne scission in cobalt–molybdenum clusters
Abstract
The alkyne complexes [Mo2(µ-C2Ph2)(CO)4(η-C5H5)2] and [Co2(µ-C2Ph2)(CO)6] reacted together to give the butterfly cluster [Co2Mo2(µ3-CPh)2(µ4-C2Ph2)(CO)4(η-C5H5)2], which can also be made from [Mo2(µ-C4Ph4)(CO)(η-C5H5)2] and [Co2(CO)8]; the possible role of the C4Ph4 complex as an intermediate in the former transformation is discussed.
