ABSTRACT:
A process for producing phosphonate esters containing the 2-(pyridyl)ethyl group by reacting a vinylpyridine with a di- or trihydrocarbylphosphite in the presence of a selected silane, protic acid, or Lewis acid is disclosed. Also disclosed are novel silylphosphonate esters containing the 2-(pyridyl)ethyl group. All of the compounds produced herein are useful as catalysts for increasing the molecular weight of polyamides.
