Abstract

The olefin-forming syn elimination of alkyl aryl selenoxides was examined. The formation of@-hydroxy selenides by addition of the elements of benzeneselenenic acid (PhSeOH) to olefin product was found to be a persistent side reaction unless an alkylamine was present during syn elimination. The selenium (I1) electrophile is provided by a comproportionation (reverse disproportionation) of PhzSez and PhSeOzH. If an intramolecular reaction is ...
