A facile and efficient method for the synthesis of (E/Z)‐α‐fluorovinyl phosphorus compounds from gem‐difluorostyrenes with diphenylphosphine oxide/dialkyl phosphate and DBU at room temperature was developed. A series of 1‐fluorovinyl phosphine oxides/phosphonates were obtained with moderate to excellent yields in these reactions. Additionally, most isomers (E/Z type) of the target compounds could be easily separated and purified by column chromatography.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
