We have developed novel fluorogenic transformations based on formation of CC bonds catalyzed by palladium using iodocoumarin 1 as a model aryl iodide, where fluorescence is quenched completely due to effects of the heavy, polarizable iodine atom. Substitution of the iodine atom for the carbon using Sonogashira, Suzuki–Miyaura and Heck couplings results in a dramatic fluorescence enhancement. This approach
