Which one of the following substances is referred to as a Gilman reagent? Organolithium reagents react with cuprous iodide to give a lithium dimethylcopper reagent, which is referred to as a Gilman reagent. Copper is +1 (that is, Cu+1), so each of the two attached alkyl groups are effectively carbanions (R−1). The cis/trans and E/Z nomenclature are used to specify the particular isomer. Now, for primary amides, all you need to do is replace the -ic acid, or -oic acid ending with the suffix “amide”..
