The ratio between 1,6- and 1,2-addition in the reactions of electrogenerated fluorenone anion radicals with RX in THF were similar to the ratio obtained in the Grignardreaction of fluorenone with RMgX in THF. This indicates that the addition products in the Grignardreaction may be obtained via the coupling of freely diffusing fluorenone anion radicals with R radicals.
