Environmentally friendly iodine(III) reagents can induce selective activation of naphthalene derivatives by a unique single-electron transfer (SET) mechanism. In their Communication on page 1301 ff., Y. Kita and co-workers describe the successful oxidative cross-coupling of unfunctionalized arenes using organoiodine(III) oxidants without need of metal catalysts. The picture emphasizes the flow of the single electrons from the hypervalent iodine(III) reagents and the green nature of the transformation.
