Although X-ray crystallography is the method of choice for the direct structural analysis of crystalline compounds, extending its use to the in situ mapping of chemical transformations involving unstable intermediates is challenging. Here this is achieved by using a porous network material as a 'reaction medium' to enable X-ray observations of reaction intermediates that are usually transient and non-isolable.
