摘要:
A compound shown by the following formula: wherein each of R1a, R2a, R3a and R4a represents a substituent selected from a non-reactive atom, a non-reactive group, a hydroxyl group and an amino group, and at least two members selected from R1a, R2a, R3a and R4a are a hydroxyl group, a carboxyl group or an amino group; is subjected to an esterification reaction or an amidation reaction with a polymerizable unsaturated compound (e.g., an alcohol, a carboxylic acid, an amine) in the presence of a catalyst comprising an element selected from the Group 3 elements, such as a samarium compound, to obtain a polymerizable adamantane derivative having at least one polymerizable unsaturated group in high yield.
