Cationic Gold Catalyzes Omega-Bromination of Terminal Alkynes and Subsequent Hydroaddition Reactions
Full text link[EN] Orthogonal sigma,pi-bisfunctionalization of terminal alkynes can be achieved with a cationic gold complex in catalytic amounts. First, the terminal C-H bond is transformed to the corresponding bromoalkyne which is then activated toward nucleophilic attack. This reactivity correlates with the structural nature of isolated gold-alkyne complexes.A.L.-P. thanks CSIC for a contract under JAE-doctors program.
