Abstract. The electrophilicity of the CF3 radical in hydrogen abstraction reactions was studied theoretically by the CNDO/2 method.

free radicals, substitution competes with hydrogen abstraction. There is evid-. enceSs that t-butoxyl radicals abstract hydrogen from anisole with the formation.

In addition, hydrogen abstraction reactions are closely related to the concentration changes of key free radicals (H, OH, HO2, etc.)
