| Abstract: | Schemes of redox transformations were proposed for osmium carbonylhydride clusters: trinuclear ( -H)Os3(-CR = CHR')(CO)1
0 (R = R' = H, Ph; R = H, R' = Ph), (-H)2Os3(3-L)(CO)9 (L = C = CHPh, CH CPh), tetranuclear CpMnOs3 (-CH = CHPh)(-H)(-CO)(CO)1
1, and trinuclear Os3(3-C = CHPh)(CO)9. Two-electron reduction of the trinuclear clusters results in elimination of the unsaturated ligand with preservation of the metal framework. |
