We review the results of our work on the iodine interaction with thioamides, selenoamides, and amides. Complexes with (i) "spoke" or "extended spoke" structures, D . I(2) and D . I(2) . I(2), respectively, (D is the ligand donor) (ii) iodonium salts of {[D(2) - I](+)[I(n)](-)} (n = 3, 7) and {[D(2) - I](+)[ FeCl(4)](-)} formulae and (iii) disulfides of the categories (a) [D - D], (b) {[D - DH](+)[I(3)](-)} have been isolated and characterized. A compound of formula {[D(2) - I](+)[I(3)](-)[D.I(2)]} containing both types of complexes (i) and ( ii) was also isolated. The interaction of diiodine with selenium analogs of the antithyroid drug 6-n-propyl-2-thiouracil (PTU), of formulae RSeU (6-alkyl-2-Selenouracil) results in the formation of complexes with formulae [(RSeU) I2]. All these results are correlated with the mechanism of action of antithyroid drugs. Finally, we review here our work on the diiodine interaction with the amides (LO). (EN)
