Four complexes of MCl4 (M=Ti, Zr, Hf) with the hypervalent trifluoromethyl iodine reagent trifluoromethyl-1,3-dihydro-3,3-dimethyl-1,2-benziodoxole (1,=L) are described. With TiCl4 , an I-O bond cleavage occurs, leading to the formation of the trifluoromethyliodonium alcoholate complexes [Ti2 Cl6 (L)4 ]Cl2 (2 a) and Ti2 Cl8 (L) (2 b). Reactions with ZrCl4 and HfCl4 form the complexes ZrCl4 (L)2 (3) and HfCl4 (L)2 (4), respectively, wherein the original I-O bond is retained and elongated compared to that in free 1. Therefore, the reactivity of 1 can be easily and practically fine-tuned by addition of different metal chlorides, following the order ZrCl4 /HfCl4
