A catalyst includes a cyclic imide compound having an N-substituted cyclic imide skeleton represented by following Formula (I): wherein X is an oxygen atom or a hydroxyl group, and having a solubility parameter of less than or equal to 26 [(MPa)] as determined by Fedors method. The catalyst may further comprise a metallic compound. By allowing (A) a compound capable of forming a radical to react with (B) a radical scavenging compound in the presence of the catalyst, an addition or substitution reaction product between the compound (A) and the compound (B) or a derivative thereof can be obtained.

The production process of the present invention comprises a step of allowing a carboxylic acid derivative represented by the formula (1):wherein ring Z is a monocyclic or polycyclic non-aromatic or aromatic ring, and Ris a halogen atom or a group represented by the formula (2):&#x2014;OR&#x2003;&#x2003;(2)wherein R is a hydrogen atom or a hydrocarbon group, to react with an organometallic compound represented by the formula (3):R-M&#x2003;&#x2003;(3)wherein Ris a hydrocarbon group, and M is a metallic atom which may have a ligand, or the formula (4):-MgY&#x2003;&#x2003;(4)wherein Y is a halogen atom,and a carboxylic acid halide represented by the formula (5):wherein Ris a hydrocarbon group or a heterocyclic group, and X is a halogen atom,to yield the tertiary alcohol ester represented by the formula (6):wherein Z, Rand Rhave the same meanings as defined above. According to the present invention, a tertiary alcohol compound having a tertiary carbon combined with a ring group can be easily and efficiently produced from carboxylic acid derivative which is comparatively cheap and readily available.

Process for preparation of tertiary alcohol esters

Adamantane derivatives in which two (meth)acryloyloxyalkyl groups are bonded with an adamantane ring through ester groups, adamantane derivatives in which two adamantane rings are bonded through an alkylene group and two urethane bonds, which two adamantane rings each have a (meth)acryloyloxy group bonded thereto directly or through a coupling group, and adamantane derivatives each having a structure in which a group containing an adamantane ring hangs on the alkylene group of an alkylene glycol di(meth)acrylate. The compounds are useful as dental materials intermediates therefor, and as intermediates for optical materials such as lenses.
