ABSTRACT:
Allylphosphonate diesters are converted to vinyl phosphonate diesters by isomerization with a catalytic amount of a ruthenium catalyst. Vinyl phosphonate derivatives are produced directly from an organo pentavalent phosphorus compound. In a particular reaction conversion of allylic phosphonate diesters to vinylic phosphonate diesters is accomplished by the transition metal mediated isomerization of the alkylphosphonate derivatives with tetrakis(triphenylphosphine)dihydrido ruthenium(II).
