A novel synthesis of α-fluoroalkylvinyl- or α-fluoroepoxyalkyl-phosphonates
Abstract
α-Fluoroalkylvinyl- or α-fluoroepoxyalkyl-phosphonates can be synthesized by the reaction of diethyl lithium phosphite with fluorinated β-oxoalkylphosphonium salts, depending upon the α-substituents R1 and R2 in the alkylidene moiety of the phosphorane used to prepare the phosphonium salts and the base used.
