In a decarboxylative coupling of alkyl N-hydroxyphthalimide esters with aryl iodides in the presence of a nickel catalyst and Zn as reducing agent, no photocatalyst, light, or arylmetal reagent is needed to form alkyl radicals from the carboxylic acid derivative. Methyl, primary, and secondary alkyl groups can all be coupled in good yield.
