Lee et al. described an approach to perform catalysis in micelles based on rod–coil block copolymers . Micelles were assembled from hydrophilic poly(ethylene oxide) (PEO) and hexa-p-phenylene, providing a platform for Suzuki reactions with the hydrophobic core acting as a suitable pocket for apolar aromatic guests [71–72]. With such a platform, full conversion was achieved at room temperature in water. Almost quantitative yields were observed when aryl chloride coupling was performed with arylboronic acids. This is indeed remarkable as aryl chlorides are generally not as reactive as aryl bromides or aryl iodides.
