| titleOfInvention | Process for preparation of tertiary alcohol esters |
| abstract | The production process of the present invention comprises a step of allowing a carboxylic acid derivative represented by the formula (1): n n nwherein ring Z is a monocyclic or polycyclic non-aromatic or aromatic ring, and R 1 is a halogen atom or a group represented by the formula (2):n n—OR (2)n nwherein R is a hydrogen atom or a hydrocarbon group, to react with an organometallic compound represented by the formula (3):n nR 2 -M (3)n nwherein R 2 is a hydrocarbon group, and M is a metallic atom which may have a ligand, or the formula (4):n n-MgY (4)n nwherein Y is a halogen atom,n nand a carboxylic acid halide represented by the formula (5): n n nwherein R 3 is a hydrocarbon group or a heterocyclic group, and X is a halogen atom,n nto yield the tertiary alcohol ester represented by the formula (6): n n nwherein Z, R 2 and R 3 have the same meanings as defined above.n n 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. |
