Title:
PROCESS FOR PRODUCING 2−ALKYL−2−ADAMANTYL &lpar METH&rpar ACRYLATE
Document Type and Number:
WIPO Patent Application WO/2002/100816
Kind Code:
A1
Abstract:
A metal 2−alkyl−2−adamantyl alcoholate [wherein the alkyl has 1 to 6 carbon atoms and the metal is lithium or −MgX (X is halogeno)] is reacted with (meth)acrylic anhydride or with an ester of a C2−8 alcohol having a double bond between the &agr − and β−positions with (meth)acrylic acid to produce a 2−alkyl−2−adamantyl (meth)acrylate. A tertiary amine compound may be added to the reaction system during the esterification, whereby the target compound can be obtained at a higher conversion.
