NMR study on the structure and stability of 4-substituted aromatic iodosyl compounds

Magn Reson Chem. 2006 Oct;44(10):955-8. doi: 10.1002/mrc.1875.

Abstract

Two 4-substituted aromatic iodosyl compounds were investigated with regard to their solubility, stability and chromatographic behaviour. 1-Iodosyl-4-methoxy- and 1-iodosyl-4-nitro-benzene are soluble in methanol and provide acceptable 1H and 13C NMR spectra; however, gradual oxidation of the solvent was observed. LC-MS analyses suggest that unlike the parent substance, iodosylbenzene, which has a polymeric structure, both compounds rather exist in the monomeric form.
