Additivity of the elctronic meta-substituent effect in 3,5-disubstituted cumyl radicals assessed by the EPR D parameter of 1,3-arylcylopentane-1,3-diyl triplet diradicals
The D parameter (EPR zero-field splitting) of the 3,3,'5,5'-tetrasubstituted diradicals 6-(X =X'=H, NO_2, CH_3, Oac, OCH_3 NH_2, and OH) were determined in a MTHF matrix at 77 K and serves as a spectroscopic tool for the determination of electronic substituent effects in multiply- substituted bdnzyl-type monoradicals through its spin density dependence.
