Gilman reagent - Wikipedia

http://www.organicreactions.org/index.php/Reactions_of_organocopper_reagents WebUnlike most other carbon nucleophiles, lithium dialkylcuprates – often called Gilman reagents – can add to acid halides just once to give ketones. The reaction between an acid halide and a Gilman reagent is not a nucleophilic acyl substitution reaction, however, and is thought to proceed via a radical pathway. [2]
