The examples presented here serve as proof-of-principle that our dual catalytic platform can be used for the one-pot construction of multiple C(sp 2 )-C(sp 3 ) bonds using readily available bromo(iodo)arene and alkyl halide starting materials and highlight the potential utility of our CEC strategy towards the discovery of novel reactions. Our method is a significant advancement over existing methodology for dialkylation of bromo(iodo)arenes, which cannot be performed in onepot and require the use of preformed organometallic nucleophiles, such as alkylbis(catecholato)silicates, that are not commercially available and generally require multistep syntheses.
