    摘要: 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 R1 is a halogen atom or a group represented by the formula (2): —OR  (2) wherein R is a hydrogen atom or a hydrocarbon group, to react with an organometallic compound represented by the formula (3): R2-M  (3) wherein R2 is a hydrocarbon group, and M is a metallic atom which may have a ligand, or the formula (4): -MgY  (4) wherein Y is a halogen atom, and a carboxylic acid halide represented by the formula (5): wherein R3 is 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, R2 and R3 have 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.
