## Abstract In the reactions of __meta__‐ and __para__‐alkyl substituted benzoic acids with aryl Grignard reagents, in tetrahydrofuran solutions and in the presence of nickel salts, the ESR spectra of the anion radicals of carboxylates derived from the benzoic acids were observed which represent th

In previous work we have reported that Grignard reagents are readily prepared by magnesium bromide capture of the anion produced from the sodium naphthalene reduction of organic halides. 1 The resultant Grignard can be reacted by conventional reagents including organometallic halides to give other
## Abstract In the reactions of alkyl‐substituted‐benzenecarboxylic and ‐2‐hydroxybenzenecarboxylic acids (ArCOOH) with alkyl‐substituted phenyl Grignard reagents (RMgX) in the presence of nickel, ketyl radicals ArCO^−^R are formed. The __para__ substituents (H, Me, Et, Isopr and __t__‐Bu) of R i
