Conclusions

The thermolysis of 2,6-di-tert-butyl-p-benzoquinone diazide in a medium of halogenated hydrocarbons was investigated by the method of chemically induced polarization of nuclei. The cyclohexadienone carbene formed during thermolysis reacts with the medium in the singlet form, while the observed polarization is the result of secondary processes, associated with the diffusion of radicals from the primary singlet radical pairs into the volume.
