Abstract

Abstract cis-and trans-9-Phenylselenoxanthene-N-(arylsulfonyl) selenilimines were synthesized and isolated. Their stereochemistry was ascertained from the NMR spectra. Cis isomers reacted with chloramine-T or-B by an SN 2 type substitution to form trans isomers, but the reverse reaction did not take place. When trans isomers were refluxed in toluene they underwent intermolecular 1, 4 rearrangement to give 9-arylsulfonamido-9- ...
