The interaction between free radicals and cobalt complexes (Co(II)TPP and Co(II)(sal)<SUB>2</SUB>(<I>R</I>-CHXDA)) has been studied using (<I>S</I>,<I>S</I>)-(−)-, (<I>R</I>,<I>R</I>)-(+)-, and <I>meso</I>-1,1′-diphenylazoethane as a radical source. The decomposition of <I>meso</I>-1,1′-diphenylazoethane by heat or UV-light in the presence of Co(II)(sal)<SUB>2</SUB>(<I>R</I>-CHXDA) having an asymmetric ligand produced an optically active (+)-2,3-diphenylbutane. The suggestion is that the α-methylbenzyl radical formed from the azo compound is stereoselectively stabilized by the Co(II)(sal)<SUB>2</SUB>(<I>R</I>-CHXDA).
