Functionalisation of cycloalkanes: the photomediated reaction of cycloalkanes with alkynes

Using a standard mercury vapour lamp or sunlight, and in the presence of a soluble or polymer-bound photomediator such as benzophenone, cycloalkanes can be functionalised by insertion of alkynes containing electron-withdrawing groups into a C-H bond.
