  3. Synthetic approaches to new three coordinate Group 6 compounds : chromium alkenyls, molybdenum thiolates and tungsten amides

    … ligands are synthesized by bromination and dehydrohalogenation of an adamantyl olefin to yield an alkenyl bromide. The Grignard reagent, derived from the bromide, is used either as a transmetallation reagent, or reacted with elemental sulfur to form a magnesium thiolate, (THF)2Mg(SC[Ad]Ar)2. …
