| titleOfInvention | Production of the esters of polycyclic compounds |
| abstract | 1,262,707. Production of the esters of polycyclic compounds. UNION CARBIDE CORP. 21 Aug., 1969 [22 Aug., 1968], No. 41754/69. Heading C2C. A process for the production of esters of polycyclic compounds of formula wherein Y represents a member of the group consisting of (i) when said polycyclic compound is fluorene or indene, (ii) when the polycyclic compound is carbazole or indole and (iii) when the polycyclic compound is an indene, R<SP>111</SP> represents hydrogen, C 1-10 alkyl and aryl of up to 10 carbon atoms, R<SP>1111</SP> represents hydrogen, C 1-10 alkyl and aryl of up to 10 carbon atoms, and aryl of up to 10 carbon atoms, and when the polycyclic compound is an indene R<SP>1111</SP> can additionally be -CH 2 -CHR<SP>1</SP>COOR, R<SP>111</SP> and R<SP>1111</SP> when taken jointly represent -CH=CH-CH=CH-, R is an alkyl group, and R<SP>1</SP> is hydrogen or methyl, comprises reacting an acrylate ester of formula CH 2 = CR<SP>1</SP>COOR with a polycyclic compound of the formula wherein X is -NH- or -CH 2 -, R<SP>11</SP> and R<SP>111</SP> individually represent hydrogen, C 1-10 alkyl, and aryl of up to 10 carbon atoms and R<SP>11</SP> and R<SP>111</SP> when taken jointly represent in the presence of a boric catalyst. The examples describe the preparation of dimethyl, diethyl, and dibutyl esters of 9,9-bis (2-carboxyethyl) fluorene; diethyl ester of 1,1-bis(2-carboxyethyl) indene; diethyl ester of 1,3-bis (carboxyethyl) indene;, ethyl-(1-indole) propionate and ethyl 3-(9-carbazole)propionate. Several other compounds are specified in Examples 16- 23. |
