无卤代烷下亚磷酸三烷基酯的重排

TRIALKYL PHOSPHITES DIRECTLY CONVERTED TO DIALKYL ALKYLPH-OSPHONATES IN THE ABSENCE OF ALKYL HALIDES

亚磷酸三烷基酯同卤化亚铜、乙腈－同回流时，它能直接重排成相应的烃基磷酸酯；与碘化亚铜回流时，亚磷酸酯的重排比与氯化亚铜有利；

By refluxing with cuprous handes in acetonitrile trialkyl phosphites can be directly converted into the corresponding dialkyl alkylphosphonate. The conversion of trialkyl phosphites with cuprous iodidees is more favorable than with cuprous chloride; The activity of the alkyl group for the rearrangement is in the order of Me>Et>Butyl.
