C-H Bond Activation and Subsequent C-C Bond Formation Promoted by Osmium:2-Vinylpyridine-Acetylene Couplings

摘要

Systems that promote C-H bond activation and subsequent C-C bond formation are of great interest,in connection with the design of metal-mediated processes for the synthesis of functionalized organic molecules from basic hydrocarbon units.An ideal process of this type would involve the entry in a consecutive and controlled way of organic fragments into a coordination transition-metal complex.To assemble the organic fragments,developing multiple selective coupling reactions of unsaturated substrates is essential.
