Synthesis of polyfluoralkylated 1,3,2-dioxaphospholane and 1,3,2-dioxaphosphorinane oxides
摘要:
Polyfluoroalkyl dichlorophosphates easily react with 1,2- or 1,3-alkanediols in a system pyridine-diethyl ether and afford 2-polyfluoroalkoxy-1,3,2-dioxaphospholane oxides or 2-polyfluoroalkoxy-1,3,2-dioxaphosphorinane oxides. In similar conditions the reaction of methyl dichlorophosphate with 1,2- and 1,3-alkanediols proceeds less effectively.
