Clusters containing carbene ligands. 3. The transformations of a (dimethylamino)methyl ligand in a triosmium cluster. The synthesis and structural characterizations of Os/sub 3/(CO)/sub 10/(. mu. -eta/sup 2/-H/sub 2/CNMe/sub 2/)(. mu. -H), Os/sub 3/(CO)/sub 9/(. mu. /sub 3/-eta/sup 2/-C(H)NMe/sub 2/)(. mu. -H)/sub 2/, and Os/sub 3/(CO)/sub 10/(. mu. -CNMe/sub 2/)(. mu. -H)
The authors have recently discovered that bis(dialkylamino)-methane compounds are effective reagents for the introduction of secondary (dialkylamino)carbene ligands into osmium carbonyl clusters. They have now examined the reaction of Os/sub 3/(CO)/sub 10/(..mu..-H)/sub 2/ with CH/sub 2/(NMe)/sub 2/. This reaction yields initially the new compound Os/sub 3/(CO)/sub 10/(..mu..-eta/sup 2/-H/sub 2/CNMe/sub 2/)(..mu..-H) which can be transformed into the compounds Os/sub 3/(CO)/sub 9/(..mu../sub 3/-eta/sup 2/-C(H)NMe/sub 2/)(..mu..-H)/sub 2/ and Os/sub 3/(CO)/sub 10/(..mu..-CNMe/sub 2/)(..mu..-H) through a sequence of C-H activation processes in the (dimethylamino)methyl group. The results of these studies are reported herein.
