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.
以下化学式所示的化合物:其中R1a、R2a、R3a和R4a中的每一个代表从非反应性原子、非反应性基团、羟基和氨基中选择的取代基,且在R1a、R2a、R3a和R4a中至少有两个成员是羟基、羧基或氨基;在催化剂的存在下,与可聚合的不饱和化合物(例如醇、羧酸、胺)进行酯化反应或酰胺化反应,所述催化剂包括从第三族元素中选择的元素,如钐化合物,以高产率获得至少具有一个可聚合不饱和基团的可聚合性金刚烷衍生物。
