Abstract:
High yields of polymerizable adamantane derivatives each having at least one polymerizable unsaturated group are produced by the esterification or amidation of a compound of general formula (1a) and a polymerizable unsaturated compound (e.g. an alcohol, a carboxylic acid or an amine) in the presence of a catalyst comprising a compound of a Group 3 element of the periodic table, such as a samarium compound. In said formula, R?1a to R4a¿ represent each a substituent selected from among inert atoms, inert groups, hydroxyl, carboxyl and amino, provided at least two groups of R?1a to R4a¿ are hydroxyl, carboxyl or amino.
