Abstract
The (μ-H)Os3{μ-OCN(Me)CH2CH=CH2}(CO)10 complex containing an allylic fragment in theN,N-dialkylsubstituted carbamoyl briding ligand was synthesized. The stereo-chemical behavior of this complex in solution was investigated. As follows from the NMR spectral data, the complex undergoes reversible conformational (about the amide C−N bond) and irreversible allylic isomerization. Both conformers were isolated in the solid state by chromatography at a reduced temperature. The allylic isomerization occurs stereospecifically to produce the (μ-H)Os3{μ-OCN(Me)CH=CHMe}(CO)10 complex with thetrans-oriented olefinic hydrogen atoms.
