The selective difluoromethylene insertion into a C–Cu bond is a challenging task and is currently limited to either a single CF2 insertion into CuCF3 or double CF2 insertions into CuC6F5 (or (Z)-CF3CF = CFCu). Achieving both selective single and double CF2 insertions into the same C–Cu bond is even more difficult. Herein, highly controllable single and double CF2 insertions into CuCF2H species with

controllable double CF2-insertion into pentafluorophenylcopper species using TMSCF3 as difluoromethylene source has been developed. The newly generated fluoroalkylcopper(I) species, C6F5CF2CF2Cu, shows good reactivity towards a myriad of structurally diverse aryl, heteroaryl and alkenyl iodides. This protocol is easy to handle, ready to scale up and applicable for the synthesis of relative complex molecules
