    • The reaction with phenyl triflate led to complete consumption and self-coupling of the triflate starting material, and resulted in the isolation of diphenyl ether in high yield (83%). Although the formation of diphenyl ether under these conditions points to a process involving the coupling between the phenyl triflate and a phenoxide nucleophile, the exact nature of the facile formation of the aryl ether is not clear at this time.

    • note
    • Although we could not rule out the possibility of the involvement of a Pd(0) species in the catalytic cycle, the formation of palladium black, which could otherwise be expected at the reaction temperature and in the absence of a stabilizing ligand, was not observed throughout the reaction except when the acrylate was used as the terminal olefin.

    • Although the reactions reported in Tables 1-3 were run on 0.5-2 mmol scales, this protocol is readily scalable as exemplified by the following reactions perfomed on a 10 mmol scale: (diagram presented)
