Abstract
AbstractReplacement of the iodine atom in an iodine (III) CF3‐transfer reagent with a Te‐aryl moiety was accomplished in a three‐step synthetic sequence. Three compounds of this type have been prepared, two of which were characterized by X‐ray diffraction. Single crystal structures were also obtained for three related Te(IV) compounds unreported so far (4a, 4b, 6b). Comparison with the iodine (III) analogues indicate a large degree of structural similarity, however these species display an interesting decomposition pathway under thermal conditions. In addition to the expected Te−CF3 bond cleavage, C−F bond cleavage is also observed, unlike in the case of iodine (III) compounds.
