Sodium tnfluoroacetate copper

Ullman type coupling occurs between aryl halides and trifluoromethyl copper species generated by the action of copper iodide on sodium tnfluoroacetate [168, 169] or on methyl fluorosulfonyldifluoroacetate [170] (equation 145) Similarly the pentafluoroethyl group can be introduced from potassium pentafluoropropion-ate [171] (equation 146)... [Pg.485]

Cheaper sources of tnfluoromelhyl groups have been the goal of several groups The use of sodium tnfluoroacetate and copper (1) iodide in dipolar aprotic solvents gave regiospecific trifluoromethylation of aromatic halides [202] (equation 136)... [Pg.703]
