Starting from the optimized conditions established for the coupling of 4-tertbutylbromobenzene and 1-bromo-3-phenylpropane we evaluated the substrate scope of the dual catalyzed method (Figure ). Initially, we explored the coupling of a range of aryl bromides, as these are more synthetically valuable than aryl iodides, with 1-bromo-3-phenylpropane (or N-(3bromopropyl)phthalimide ). Our system exhibits a wide functional group tolerance, as demonstrated by the coupling of electronically diverse substrates (4a-4c) and substrates with reducible functional groups, such as nitriles (4d), sulfones (4e), aldehydes (4f), ketones (4g), esters (4h), and amides (4i). When 1-bromo-4-chlorobenzene (4j) is used as a substrate, our system is selective for coupling the aryl bromide, which offers opportunities for orthogonal reactivity with traditional cross-coupling reactions. Substrates with protic functionality, such as 4bromophenethyl alcohol (4k) and 5-bromoindole (4l) could also be coupled in high yield, although 4-bromoaniline gives a reduced yield (see SI) and the more activated 4-iodoaniline (4m) is required to give a high yield. Mono-ortho-substituted substrates with moderate steric bulk (4n & 4o) are also effectively coupled.
