The activation of iodomethane by the Cr(II) complex 1 to form the Cr(III) iodide and Cr(III) methyl compounds 2 and 3 was monitored by UV−visible spectroscopy. The Cr(III) halide species were independently synthesized by oxidation of 1 with lead(II) halides, the Cr(III) methyl compound was prepared via salt metathesis of the Cr(III) triflate, and their structures were determined by single-crystal X-ray diffraction.
