The anodic fluorination of aryl propargyl sulfides in DME containing a fluo
ride supporting electrolyte using an undivided cell provided the correspond
ing alpha -mono- and alpha,alpha -difluorinated sulfides selectively, depen
ding on the amount of electricity passed. The alpha -monofluorinated sulfid
es were readily converted into the corresponding alpha -fluoroallenyl sulfi
des in good to moderate yields. (C) 2001 Elsevier Science Ltd. All rights r
