Clusters containing carbene ligands. 9. Reaction of MeC triple bond CNMe sub 2 with Os sub 3 (CO) sub 10 (. mu. -H) sub 2
- Univ. of South Carolina, Columbia (USA)
The reaction of Os{sub 3}(CO){sub 10}({mu}-H){sub 2} with MeC{triple bond}CNMe{sub 2} at 25{degree}C yielded the new complex Os{sub 3}(CO){sub 10}({mu}-C(Me)C(H)NMe{sub 2})({mu}-H) (1, 68%) by the addition and insertion of MeC{triple bond}CNMe{sub 2} into one of the metal-hydrogen bonds. When heated to 68{degree}C in hexane, 1 isomerized to the new complex Os{sub 3}(CO){sub 10}({mu}-CH(Me)CNMe{sub 2})({mu}-H) (2) by a shift of the hydrogen atom from the NMe{sub 2}-substituted carbon atom to the methyl substituted carbon atom. At 68{degree}C, 2 was slowly decarbonylated to yield the new compound Os{sub 3}(CO){sub 9}({mu}{sub 3}-MeC{sub 2}NMe{sub 2})({mu}-H){sub 2} (3). In a competing reaction 2 simultaneously isomerized to the new compound Os{sub 3}(CO){sub 10}({mu}-C(Et)N(Me)CH{sub 2})({mu}-H) (4). When heated to 97{degree}C for 36 h, 3 isomerized to the new compound Os{sub 3}(CO){sub 9}({eta}{sup 3}-CH(Me)C(H)NMe{sub 2})({mu}-H) (5), which exists in solution as a mixture of isomers. One of the isomers was crystallized and characterized structurally. Compounds 1-5 were all characterized by IR, NMR, and single-crystal X-ray diffraction analyses.
