Abstract
Metal-iodosylarene complexes have been recently viewed as a second oxidant alongside of the well-known high-valent metal-oxo species. Extensive efforts have been exerted to unveil the structure-function relationship of various metal-iodosylarene complexes. In the present manuscript, density functional theoretical calculations were employed to investigate such relationship of a specific manganese-iodosylbenzene complex [MnIII(TBDAP)(PhIO)(OH)]2+ (1). Our results fit the experimental observations and revealed new mechanistic findings. 1 acts as a stepwise 1e+1e oxidant in sulfoxidation reactions. Surprisingly, C-H bond activation of 9,10-dihydroanthracene (DHA) by 1 proceeds via a novel ionic hydride transfer/proton transfer (HT/PT) mechanism. As a comparison to 1, the electrophilicity of an iodosylbenzene monomer PhIO was investigated. PhIO performs concerted 2e-oxidations both in sulfoxidation and C-H activation. Hydroxylation of DHA by PhIO was found to proceed via a novel ionic and concerted proton-transfer/hydroxyl-rebound mechanism involving 2e-oxidation to form a transient carbonium species.

Abstract
In the title mol-ecule {systematic name: N-[3-(diquino[3,2-b;2',3'-e][1,4]thia-zin-6-yl)prop-yl]-4-methyl-benzene-sulfon-amide}, C28H24N4O2S2, the penta-cyclic system is relatively planar [maximum deviation from the mean plane = 0.242 (1) Å]. The dihedral angle between two quinoline ring systems is 8.23 (2)° and that between the two halves of the 1,4-thia-zine ring is 5.68 (3)°. The conformation adopted by the 3-(p-tolyl-sulfonyl-amino)-propyl substituent allows for the formation of an intra-molecular N-H⋯N hydrogen bond and places the benzene ring of this substituent above one of the quinoline fragments of the penta-cyclic system. In the crystal, mol-ecules are arranged via π-π stacking inter-actions into (0-11) layers [centroid-centroid distances = 3.981 (1)-4.320 (1) Å for the rings in the penta-cyclic system and 3.645 (1) Å for the tolyl benzene rings]. In addition, mol-ecules are involved in weak C-H⋯O, which connect the layers, and C-H⋯S hydrogen bonds. The title compound shows promising anti-cancer activity against renal cancer cell line UO-31.

Abstract
The I(2)-adducts of drugs propylthiouracil (PTU) and methimazole (MeImSH) oxidize liquid mercury in dichloromethane to separate in good yield the neutral complexes [HgI(2)(PTU)(2)·MeOH] (1), [HgI(2)(PTU)(2)·HgI(2)] (2), and [Hg(2)I(4)(MeImSH)(2)] (3). The single crystal X-ray diffraction analysis of 1-2 shows that the Hg(II) center is coordinated by two sulfur atoms and by two iodine atoms in a tetrahedral geometry. In complex 2 almost linear molecules of HgI(2) result encapsulated in the crystal packing enfolded by the hydrophobic propyl appendages of coordinated units of PTU. X-ray analysis of complex 3 shows the presence of dimeric [Hg(2)I(4)(MeImSH)(2)] molecules to form Hg(2)S(2)I(4) cores. The intra- and intermolecular hydrogen bonds concerning PTU and MeImSH have been evaluated. The oxidation of Hg(0) to Hg(II) requires a two-electron transfer process accomplished by an oxidative addition from the "activated" iodine moiety. The oxidizing and complexing properties of PTU-I(2) and MeImSH-I(2) have been interpreted considering the S-donor to I(2) interaction that leads to a charge separation between the sulfur-bound iodine atom S-I and the terminal I atom. Compounds 1, 2, and 3 react with tetraethylammonium iodide to separate the compound (Et(4)N)(2)[HgI(4)] with the release of free PTU and MeImSH, respectively. The reported dissolution technique could be applied to the recovery of mercury from waste electrical and electronic equipment (WEEE) scrap, the nature of complexes 1-3 makes it possible the easy separation of the mercury as tetraiodomercurate anion and the recycling of the donors.
