formed during Sonogashirareactions; after complete reaction the solution retains a characteristic light color (see picture). Very sluggish Sonogashirareactions of electron‐enriched aryl diiodides have been carried out in high yield in an oxygen‐free, two‐chamber reactionsystem. The formation of triethylamine hydroiodide crystals was monitored to determine the completion of reaction.
