Article abstract of DOI:10.1016/0040-4039(96)01267-1

Application of the published reaction conditions for the Wadsworth-Emmons transformation of ketones or aldehydes into 1,1-difluoroolefins with lithium difluoromethylenephosphonate failed to give the expected product, affording instead phosphates of the ge
