ADAMANTANE DERIVATIVES AND PROCESS FOR PRODUCING THE SAME
First Claim
1. An adamantane derivative, characterized by comprising a structure represented by a general formula (I):
- where R represents a hydrogen atom, a methyl group, or a CF3 group, Ys each represent an alkyl group having 1 to 10 carbon atoms, a halogen atom, or a hydroxyl group, or two Ys are coupled to form ═
O, and multiple Ys may be identical to or different from each other, R1 represents an alkyl group or a cycloalkyl group having 1 to 10 carbon atoms, and may contain a hetero atom and/or a nitrile group in part of its structure, k represents an integer of 0 to 14, and m and n each independently represent an integer of 0 to 4.

Abstract
The present invention provides an adamantane derivative (I) having a structure represented by the general formula (I); an adamantane derivative (II) having a structure represented by the general formula (II); and a process for producing those adamantane derivatives. An alcohol form of an adamantane compound is reacted with a sulfonyl compound to obtain the adamantane derivative (II), which is then reacted with an alcohol to obtain the adamantane derivative (I). The adamantane derivative (I) and adamantane derivative (II) each having the structure represented by the general formula (I) and general formula (II), respectively, is a novel adamantyl (meth)acrylate compound and useful as a monomer for functional resins such as a photosensitive resin in the field of photolithography.
