Abstract
Official abstract text for this publication.
A method for producing tricyclo[5.2.1.02,6]decane-2-carboxylate according to the present invention is a method for producing tricyclo[5.2.1.02,6]decane-2-carboxylate, containing reacting tricyclo[5.2.1.02,6]deca-3-ene in a dilute solution containing the tricyclo[5.2.1.02,6]deca-3-ene with carbon monoxide in the presence of an acid catalyst, followed by reaction with an alcohol, wherein the dilute solution contains 100 parts by mass or more of a tricyclo[5.2.1.02,6]decane isomer mixture based on 100 parts by mass of the tricyclo[5.2.1.02,6]deca-3-ene, the tricyclo[5.2.1.02,6]decane isomer mixture contains endo-tricyclo[5.2.1.02,6]decane (Endo form of TCD) and exo-tricyclo[5.2.1.02,6]decane (Exo form of TCD), and a constituent ratio thereof (Endo form of TCD/Exo form of TCD) is greater than 1.0.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing tricyclo[5.2.1.0 2,6 ]decane-2-carboxylate, the method comprising: reacting tricyclo[5.2.1.0 2,6 ]deca-3-ene in a dilute solution comprising the tricyclo[5.2.1.0 2,6 ]deca-3-ene with carbon monoxide in the presence of an acid catalyst, followed by reaction with an alcohol to produce tricyclo[5.2.1.0 2,6 ]decane-2-carboxylate, wherein the dilute solution comprises 100 parts by mass or more of a tricyclo[5.2.1.0 2,6 ]decane isomer mixture based on 100 parts by mass of the tricyclo[5.2.1.0 2,6 ]deca-3-ene, the tricyclo[5.2.1.0 2,6 ]decane isomer mixture comprises endo-tricyclo[5.2.1.0 2,6 ]decane and exo-tricyclo[5.2.1.0 2,6 ]decane, and a constituent ratio of endo-tricyclo[5.2.1.0 2,6 ]decane to exo-tricyclo[5.2.1.0 2,6 ]decane is greater than 1.0. 2. The method according to claim 1 , wherein an amount of the acid catalyst used is from 4 to 25-fold moles based on the tricyclo[5.2.1.0 2,6 ]deca-3-ene. 3. The method according to claim 1 , wherein in reacting the tricyclo[5.2.1.0 2,6 ]deca-3-ene in the dilute solution comprising the tricyclo[5.2.1.0 2,6 ]deca-3-ene with the carbon monoxide, a partial pressure of the carbon monoxide is from 0.5 to 5 MPaG. 4. The method according to claim 1 , wherein the alcohol comprises ethanol. 5. The method according to claim 1 , wherein the acid catalyst is a catalyst comprising hydrogen fluoride. 6. The method according to claim 1 , wherein the constituent ratio of endo-tricyclo[5.2.1.0 2,6 ]decane to exo-tricyclo[5.2.1.0 2,6 ]decane is greater than 1.5. 7. The method according to claim 1 , wherein the constituent ratio of endo-tricyclo[5.2.1.0 2,6 ]decane to exo-tricyclo[5.2.1.0 2,6 ]decane is 100:0.
