Oxygenhydrogen versus nitrogenoxygen bond cleavage in the oxidative addition of oximes to [Os3(CO)10(MeCN)2]: crystal structures of the isomers [Os3H(Me2CNO)(CO)10] and [Os3(OH)(Me2CN) (CO)10]

摘要: Acetone oxime (Me2CNOH) reacts with [Os3(CO)10(MeCN)2] to give the bridging oximato cluster [Os3(μ-H)(μ-Me2CNO)(CO)10] (1) resulting from oxidative addition OH bond cleavage. An X-ray crystal structure determination showed that ligand is two osmium atoms by bonding one Os atom through N-atom and another O-atom. A range of clusters similarly bonded ligands were synthesised oximes derived benzophenone (Ph2CNOH), cyclohexanone (C6H10NOH), acetaldehyde (MeCHNOH), benzaldehyde (PhCHNOH) (two isomers obtained), formamide (NH2CHNOH). Compound 1 isomerises at 125°C non-hydrido isomer [Os3(μ-OH)(μ-Me2CN)(CO)10] (2) which was characterised spectroscopically crystallographically shown contain hydroxy N-bonded Me2CN ligands. Overall NO cleavage has been achieved an initial followed isomerisation.
