Substitution of the osmium(I) dimer [Os2(MeCO2)2(CO)6] with monophosphines has been previously shown to give mono- and disubstituted products with the introduced ligands exclusively trans to the OsOs bond. This has allowed the preparation of the c

Tropone (cycloheptatrienone, C7H6O) reacts in refluxing cyclohexane with [Os3H2(CO)10] to give the oxidative addition product [Os3H(C7H5O)(CO)10](1), also formed from [Os3(CO)10(MeCN)2], and the insertion product [Os3H(C7H7O)(CO)10](2). Structures ba

Substitution reactions of the osmium(I) dinuclear compound [Os2(MeCO2)2(CO)6]. X-Ray crystal structure of [N(PPh3)2][Os2(MeCO2)2Cl(CO)5]

The dinuclear osmium(I) compound [Os2(MeCO2)2(CO)6] has labile axial CO ligands and there is no evidence for equatorial substitution in its reactions. Refluxing tetrahydrofuran (thf) gives [Os2(MeCO2)2(CO)5(thf)] which reacts with tertiary phosphines
