Through ligand exchange reaction of Vaska's complex with a chelating diphosphinite ligand containing a cyclopropyl group, CH activation rather than CC activation of the strained cyclopropyl ring is induced. The activation takes place as a second step preceded by the ligand exchange reaction. The fixation of the CH bond near to the metal through the geometry of the diphosphinite ligand is essential for the activation process.
