PROCESS FOR PRODUCING a-SUBSTITUTED NORBORNANYL ACRYLATES

摘要

Disclosed is a process for efficiently producing a-substituted norbornanyl acrylates on a commercial scale while suppressing the production of by-products derived, for example, from intermolecular cyclization and overaddition to acrylic acid.  The a-substituted norbornanyl acrylates are useful as norbornene-type resist monomers.  An a-substituted acrylic acid is reacted directly with a substituted norbornene in the presence of at least one acid catalyst selected from methanesulfonic acid and camphorsulfonic acid.  According to this reaction, the production of by-products derived, for example, from intermolecular cyclization and overaddition of the acid to the product can be suppressed.
