Sluggish σ-Bond Formation between sp-Hybridized Carbons:  Acetylide Coupling on Ag(111)

Chemisorbed methylacetylide intermediates were generated on clean Ag(111) to study the mechanism and kinetics of C−C σ-bond formation between sp-hybridized carbon centers. Following the adsorption of propynyl iodide (C3H3I) at 110 K, surface heating led to the cleavage of the C−I bond at 200 K, and...
