Palladium catalyst voyage prompts carbon–carbon bond formation rethink

Ingenious fluorescence microscopy experiments have revealed palladium atoms’ liberated behaviour, helping answer unresolved questions about an important process for forming bonds between carbon atoms. The Suzuki–Miyaura cross-coupling won Akira Suzuki a Nobel prize in chemistry in 2010, but there has been debate about whether solid palladium catalysts are dissolving or not.
