Acylthio- or acylselenoureas react with silver oxide to form
tetranuclear silver(I) complexes containing the deprotonated
acylchalcogenourea ligands binding to the silver atoms via the chalcogen
and oxygen atoms. These tetrasilver(I) species react with either four or
eight equivalents of a phosphine giving either dinuclear silver(I)
phosphine complexes or tetrahedral silver diphosphine complexes. In
these compounds too, the acylchalcogenourea ligands form sixmembered
rings coordinating to the metal through the chalcogen and
oxygen atoms. In one case we observed a very rare example of an
acylthiourea ligand coordinating through the nitrogen and sulfur atoms,
resulting in a four-membered ring. A silver(I) complex containing a
deprotonated acylselenourea and an N-heterocyclic carbene ligands is
also reported. This was prepared from the corresponding acetate
derivative and the acylselenourea; the acetate in this case acts as the base.
All compounds reported were characterised by spectroscopic techniques
and many also by X-ray diffraction.

Nucleophilic Iodonium Interactions (NIIs) in 2-coordinate Iodine(I) and Silver(I) Complexes
Ward, Jas S; Frontera, Antonio; Rissanen, Kari (Royal Society of Chemistry (RSC), 2021)The generality of nucleophilic iodonium interactions (NIIs) has been demonstrated by preparing a range of silver(I) and iodonium (I+) complexes and studying their 15N NMR chemical shifts, with the first example of a ... -
Do 2-coordinate iodine(I) and silver(I) complexes form Nucleophilic Iodonium Interactions (NIIs) in solution?
Wilcox, Scott; Sethio, Daniel; Ward, Jas S; Frontera, Antonio; Lindh, Roland; Rissanen, Kari; Erdelyi, Mate (Royal Society of Chemistry (RSC), 2022)The interaction of a [bis(pyridine)iodine(I)]+ cation with a [bis(pyridine)silver(I)]+ cation, in which an iodonium ion acts as nucleophile by transferring electron density to the silver(I) cation, is reinvestigated herein. ... -

Linear bis‐Coordinate Silver(I) and Iodine(I) Complexes with R3R2R1N Tertiary Amines
Kumar, Parveen; Komulainen, Joonas; Frontera, Antonio; Ward, Jas S.; Schalley, Christoph; Rissanen, Kari; Puttreddy, Rakesh (Wiley-VCH Verlag, 2023)Homoleptic [L–I–L]⁺ iodine(I) complexes (where L is a R3R2R1N tertiary amine) were synthesized via the [L–Ag–L]⁺ → [L–I–L]⁺ cation exchange reaction. In solution, the amines form [R3R2R1N-Ag-NR1R2R3]⁺ ... -
Iodine(I) and Silver(I) Complexes Incorporating 3-Substituted Pyridines
Rissanen, Kari; Ward, Jas S. (American Chemical Society (ACS), 2023)Building upon the first report of a 3-acetaminopyridine-based iodine(I) complex (1b) and its unexpected reactivity toward tBuOMe, several new 3-substituted iodine(I) complexes (2b–5b) have been synthesized. The iodine(I) ...
