Abstract

- Published data available by now on the use of correlation analysis in the free-radical chemistry are discussed systematically. The scales of <> sigma -constants of substituents proposed previously are analysed. It is shown that none of them is suitable as a general scale because almost in all cases, it is impossible to separate correctly the proper radical and polar contributions to the overall effect of substituents. A new approach to the quantitative estimation of the relationship between the structure and reactivity of molecules in free-radical processes is proposed and called r(-2)-analysis.
