Adamantane derivatives are represented by Formula (1), (6) or (9) :
[In Formula (1), R1 is a hydrogen atom or a methyl group; each of R2 and R3 is, identical to or different from each other, a hydrogen atom or a methyl group; each of A1 and A2 is, identical to or different from each other, a -C(=O)-O- group or -O-C(=O)- group, where the right-hand side of these two groups is on the adamantane ring side; each of X1 and X2 is, identical to or different from each other, a straight- or branched-chain alkylene group having 1 to 12 carbon atoms. In Formula (6), each of R4 and R5 is, identical to or different from each other, a hydrogen atom or a methyl group; each of R6 and R7 is, identical to or different from each other, a hydrogen atom or a methyl group; each of A3 and A4 is, identical to or different from each other, a group represented by the following formula:-A5-O-C(=O)- (wherein A5 is a straight- or branched-chain alkylene group having 1 to 6 carbon atoms, where the right-hand side of the above formula is on the adamantane ring side);
X is a straight- or branched-chain alkylene group having 1 to 12 carbon atoms; and each of m and n is 0 or 1. In Formula (9), R8 is a hydrogen atom or a methyl group; each of R9 and R10 is, identical to or different from each other, a hydrogen atom or a methyl group; R11 is a hydrogen atom, a straight- or branched-chain alkyl group having 1 to 4 carbon atoms, or a group represented by the following Formula (10):
(wherein R12 is an acryloyl group, methacryloyl group, 1-adamantylcarbonyl group or 3,5-dimethyladamant-1-ylcarbonyl group; and s is an integer from 1 to 6); and each of p, q and r is an integer from 1 to 6.] These adamantane derivatives are useful as, for example, raw materials for dental materials.
