    Abstract: Phosphonic esters I ##STR1## (A is an aromatic radical or an .alpha., .beta.-olefinically unsaturated group and R.sup.1 is C.sub.1 -C.sub.4 -alkyl or phenyl) are prepared by subjecting a phosphite II ##STR2## to a rearrangement reaction in the presence of a catalytic amount of a halide ion-donating compound to give I. The compounds I are used as intermediates for organic syntheses, in particular for the synthesis of polyenes.
