Mechanochemically induced cross-dimerizations of nitrosobenzenes. Kinetics and solid-state isotope effects

Mechanical treatment (milling) of crystals of aromatic nitroso dimers (azodioxides) induces their dissociation and cross-dimerizations. The mechanisms of these processes are discussed on the basis of kinetic studies and the solid-state 15N kinetic isotope effect, which is measured for the first time. By comparison with analogous processes in co-crystals and in melts, it appears that the reactions follow similar mechanism in which the surface deformations play the crucial role. The system can also be used as a model for more general conceptual study of solid-state reaction mechanisms.
