Abstract
Rapid oxidative addition of Ph3PCHCHO at [Os3(CO)10(MeCN)2] gives the isomers [Os3H(µ-Ph3PCCHO)(CO)10](1) and [Os3H(µ-Ph3PCHCO)(CO)10](2)(X-ray structures reported) which decarbonylate to give the clusters containing triply-bridging ligands: [Os3H(Ph3PCCHO)(CO)9](3), [Os3H2(C6H4PPh2CCHO)(CO)8](5), and [Os3H(Ph3PCHCO)(CO)9](4)(as two isomers).Keywords
