Functionalisation of cycloalkanes: The photomediated reaction of cycloalkanes with alkynes
Geraghty, Niall W.A,Hannan, John J
, p. 3211 - 3213 (2001)
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.
