Asymmetric [N-I-N]+ halonium complexes

Chem Commun (Camb). 2020 Jul 28;56(60):8428-8431. doi: 10.1039/d0cc02758h.

Abstract

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 were characterised by 1H and 1H-15N HMBC NMR spectroscopy, and single crystal X-ray crystallography.
