    • It should be noted that there is no reaction between 1 and phenylacetylene in the absence of the palladium catalyst. In the absence of CuI, the reaction does occur, albeit at a slower rate. See supporting information for exact procedure used and complete details of the GC analysis.

    • We have established that similar results are obtained when 4-nitrobromobenzene is employed as the electrophilic substrate instead of 1.
