Abstract：

A　new　copper-mediated　trifluoromethylation　reaction　using　copper(i)　chlorodifluoroacetate　complexes　as　reagents　is　reported.　The　complex　[L2Cu][O2CCF2Cl]　(L　=　bpy,　dmbpy,　phen)　reacted　with　(hetero)aryl　iodides　and　bromides　in　the　presence　of　CsF　in　DMF　at　75　°C　to　afford　the　trifluoromethylarenes　in　good　to　excellent　yields.　High　compatibility　with　various　chemical　functions　or　(hetero)cycles　was　also　observed　in　the　reaction.　A　reaction　mechanism　involving　a　difluorocarbene　intermediate,　along　with　a　subsequent　formation　of　a　-CF3　anion　was　proposed.　©　The　Royal　Society　of　Chemistry　2016.
