Assessment of the solution equilibria of [bis(pyridine)iodine(I)]+ complexes by ESI-MS and NMR reveals the preference of iodine(I) to form complexes with a more basic pyridine. Mixtures of symmetric [bis(pyridine)iodine(I)]+ complexes undergo statistical ligand exchange, with a predominant entropic driving force favoring asymmetric systems. The influence of ligand basicity, concentration, temperature, and ligand composition is evaluated. Our findings are expected to facilitate the investigations, and the supramolecular and synthetic applications of halonium ions’ halogen bonds.

Asymmetric [N–I–N]+ halonium complexes
Ward, Jas S.; Fiorini, Giorgia; Frontera, Antonio; Rissanen, Kari (Royal Society of Chemistry, 2020)The first asymmetric halogen-bonded iodonium complexes [I(py)(4-DMAP)]PF6 (2c) and [I(py)(4-Etpy)]PF6 (2e) were prepared via [N-Ag-N]+ → [N-I-N]+ cation exchange of their analogous 2-coordinate silver complexes. The complexes ... -
Exploiting the Chiral Ligands of Bis(imidazolinyl)- and Bis(oxazolinyl)thiophenes : Synthesis and Application in Cu-Catalyzed Friedel–Crafts Asymmetric Alkylation
Islam, Mohammad Shahidul; Alammari, Abdullah Saleh; Barakat, Assem; Alshahrani, Saeed; Haukka, Matti; Al-Majid, Abdullah Mohammed (MDPI AG, 2021)Five new C2-symmetric chiral ligands of 2,5-bis(imidazolinyl)thiophene (L1–L3) and 2,5-bis(oxazolinyl)thiophene (L4 and L5) were synthesized from thiophene-2,5-dicarboxylic acid (1) with enantiopure amino alcohols (4a–c) ... -

Yu, Shilin; Truong, Khai-Nghi; Siepmann, Marcel; Siiri, Arto; Schumacher, Christian; Ward, Jas S.; Rissanen, Kari (American Chemical Society, 2023)A series of LH[Z–I–Z] halogen(I) complexes, where Z = saccharinato or phthalimido anions and LH = pyridinium, pyrazinium, tetrabutyl (TBA)- or tetramethylammonium (TMA) cations, were prepared, structurally characterized, ... -
Asymmetric Ring Opening in Tetrazine‐based Ligand Affording a Tetranuclear Opto‐Magnetic Ytterbium Complex
Richardson, Paul; Marin, Riccardo; Zhang, Yixin; Gabidullin, Bulat; Ovens, Jeffrey; Moilanen, Jani O.; Murugesu, Muralee (Wiley-VCH Verlag, 2021)We report the formation of a tetranuclear lanthanide cluster, [Yb 4 (bpzch) 2 (fod) 10 ] ( 1 ), which occurs from a serendipitous ring opening of the functionalized tetrazine bridging ligand, bpztz (3,6‐dipyrazin‐2‐yl‐1, ... -
