Patent ID: 7385079

Claim:
A process for producing an α-substituted acrylic norbornanyl compound represented by the formula [3], wherein R 1 represents a hydrogen atom, methyl group, ethyl group, n-propyl group, isopropyl group, n-butyl group, sec-butyl group, tert-butyl group, fluoromethyl group, difluoromethyl group, trifluoromethyl group, or perfluoroethyl group, and wherein one of R 2 , R 3 and R 4 is a CF 3 C(CF 3 )(OH)CH 2 — group, and each of the other two of R 2 , R 3 and R 4 is a hydrogen, the process comprising reacting an α-substituted acrylic acid anhydride represented by the formula [1], wherein R 1 is defined as above, with a substituted norbornanyl alcohol represented by the formula [2], wherein R 2 , R 3 and R 4 are defined as above; and wherein the reaction is conducted in the presence of at least one additive that is an organic sulfonic acid or Lewis acid at a temperature of −50° C. to +60° C., or the reaction is conducted in the absence of any organic sulfonic acid or Lewis acid at a temperature of +20° C. to +200° C.
