  • Method for manufacturing phosphonate esters
    Patent number: 7166737
    Abstract: The present invention relates to a new manufacturing method for phosphonate esters, which have utility as a carbon-carbon binding formation agent, as well as a synthesis intermediate for biologically active substances such as medical drugs and agri-chemicals. Specifically the present invention relates to a new industrially advantageous manufacturing method for phosphonate esters in which the phosphonate esters of the subject can be efficiently obtained with a high yield rate through a simple operation while having barely any side reaction or sub-product. More specifically, the present invention pertains to a manufacturing method for phosphonate esters in which secondary phosphonate esters and alkene compounds are reacted in a transition metal catalyst. In addition the present invention relates to a new manufacturing method for allylphosphonate esters in which secondary cyclic phosphonate esters and 1,3-diene compounds are reacted in a palladium catalyst.
    Type: Grant
