1H and 13C-CIDNP spectra were obtained during the thermal decomposition of several arylazo aryl sulfones (Ar-N=N-SO2-Ar') in tetrachloroethylene or 1,1,2,2-tetrachloroethane at 100 deg C.An enhanced absorption from the C1 of the starting material, azo sulfone, was observed; this indicates that the decomposition of azo sulfone proceeds by means of one-bond fission.The formation of sulfones (ArSO2Ar') and sulfinic esters (ArO(SO)Ar') as recombination products in a solvent cage was established from the signs of polarization (enhanced absorption or emission).
