Se-Demethylation from 8-dimethylamino-1-methylselanylnaphthalene and its Se-oxide: an X-ray structure of a stable selenenic anhydride with a 8-dimethylamino-1-naphthyl ligand: peri Se ⋯ N interaction
Abstract
Reaction of a selenoxide, 8-dimethylamino-1-methylseleninylnaphthalene 2, with acetic anhydride gave exclusively the Se-demethylated product, the corresponding selenoperacetate 3; the X-ray crystal structure of the stable selenenic anhydride 6 derived from hydrolysis of 3 shows the strong intramolecular interactions between selenium and nitrogen atoms.
