Metal complexes of diaryl and 2,2′-dipyridyl disulfides

Novel Copper(II) Thiodibenzoic Acid Coordination Polymers by in situ Extrusion of Sulfur from 2,2′‐Dithiodibenzoic Acid and the Unique Oxidation of Disulfide to Sulfate

“…It is reported in literature that heterocyclic disulfide compounds can undergo either insertion or extrusion of sulfur or oxidation of sulfur to sulfonate ion 19,26–31. Such S–S and C–S cleavage and rearrangement reaction or oxidation generally proceed under solvothermal conditions32–34 via oxidative cleavage, radical‐assisted cleavage or nucleophilic cleavage, accompanied by a change in oxidation state of the metal in some cases 35.…”

“…Such S–S and C–S cleavage and rearrangement reaction or oxidation generally proceed under solvothermal conditions32–34 via oxidative cleavage, radical‐assisted cleavage or nucleophilic cleavage, accompanied by a change in oxidation state of the metal in some cases 35. In a previous study, Zhu et al reported the reaction of bis[4‐pyridin‐2‐yl)pyrimidinyl] disulfide (ppds) with Cu(NO 3 ) 2 under ambient temperature, in which ppds was turned into its trisulfide 2‐ppts and monosulfide 2‐pps, prior to coordination 19. They also observed that such oxidative cleavage and rearrangement were not effective with other aromatic disulfides 36.…”

“…The disulfide atoms can remain either uncoordinated or take part in weak interactions. As exemplified in literature, the S–S bond can also undergo diversified changes such as oxidative or reductive cleavage, extrusion of one sulfur or insertion of one additional atom (S, C, N) and can adopt mononuclear, hexanuclear, 1D chain, 2D sheet, and novel 3D frameworks 17–19. The presence of different co‐ligands such as phenanthroline and bipyridine can influence the structural features of the complexes formed and can lead to the formation of new products with reduced dimensionality of the networks formed 20.…”

Slow diffusion in situ ruthenium/ligand reaction: Crystal structures, fluorescence and biological properties

“…Up to now, a series of transition metal complexes have been found to react with 2,2'-dithiodibenzoic acid (dtdb), giving rise to 1D chains, 2D sheets or 3D network whereby the carboxylate act as monodentate or bidentate donor with or without cleavage of the S-S bond [9]. Recently, we have isolated new copper(II) coordination polymers, whereby dtdb underwent simultaneous S-S and C-S scission under slow diffusion conditions, leading to the formation of 1D coordination polymers [10].…”

“…In this respect, the use of organosulfur compounds containing carboxylate groups can be attractive due to their flexibility and versatile coordinating modes of both sulfur and oxygen atoms and, generating unprecedented coordination frameworks M A N U S C R I P T ACCEPTED MANUSCRIPT 2 which can act as linkers between inorganic moieties [4][5][6][7][8].
