Key words
palladium catalysis - photocatalysis - cross-electrophile coupling - biaryl coupling
Significance
Maiti and co-workers report a highly chemoselective cross-coupling of (hetero)aryl halides under palladium visible-light catalysis. Key to success was ligand design enabling differing modes of oxidative addition between the (pseudo)halides.
Comment
Support for the proposed hybrid aryl Pd(I)-radical species was achieved by trapping the corresponding species with N-methyl pyrrole and DMPO. The corresponding DMPO adduct was subsequently characterized by EPR.
