Fluoro-benzeneselenenylation of electron-deficient alkenes with benzeneselenenyl fluoride [PhSeF] generated in situ by the reaction of diphenyl diselenide and xenon difluoride proceeded smoothly in dichloromethane. The product yields increased remarkably in higher concentration of the seleno-reagent. The reactive seleno-reagent PhSeF may be stabilized in the higher concentration presumably by the favorable association of the reagent. (C) 2000 Elsevier Science S.A. All rights reserved.
