We herein describe a parallel comparison between homogeneous and heterogeneous coppercatalysts for microwave-assisted direct CH bond arylation. These catalytic systems feature enhanced catalytic activities, unique bulky ligand/base effects, mild conditions, and operational simplicity with reduced catalyst loadings and shortened reaction times. A wide range of synthetically challenging multi-substituted
