Sažetak
Thermal dimerization of nitroso compounds in the solid state was investigated by using p- substituted nitrosobenzenes as a model compounds. Mechanism that includes interplay between topochemical reaction trajectories and phase transfer was proposed on the basis of FT-IR spectroscopic kinetics, time resolved powder diffraction and low temperature x-ray structure determination. From shapes of the kinetics curves analyzed on the basis of Avrami model, it was found that phase transfer can be triggered by dimerization reaction of p-substituted nitrosobenzene to azodioxide, which, in turn, can be caused by different packing factors such as disorder in the starting nitroso monomer crystals. Since the represented model can be extended to broad series of compounds, we propose it as a general method for investigations of solid-state reaction mechanisms.
