Abstract
1377247 Substituted pyrazolines CIBAGEIGY AG 14 April 1972 [19 April 1971] 17363/72 Heading C2C [Also in Divisions C5 and C3] Novel pyrazoline compounds of formula.... wherein R 1 represents H, C 1-15 alkyl or phenyl optionally substituted by non-chromophoric groups, R 2 and R 3 (independently) denote H or methyl, R 4 represents CF 3 , CN, a COOR, CONRR<SP>1</SP> or SO 2 NRR<SP>1</SP> radical, wherein R and R<SP>1</SP> independently represent H or C 1-4 alkyl optionally substituted by hydroxyl, alkoxy, amino, sulphonic acid or carboxylic acid, or R and R<SP>1</SP> together with the nitrogen represent optionally methyl-substituted morpholino, pyrrolidino or piperidino, or R 4 represents the -SO 2 R<SP>11</SP> radical, wherein R<SP>11</SP> represents H or C 1-4 alkyl optionally substituted by OH, alkoxy, amino, sulphonic acid or carboxylic acid, or C 2-4 alkenyl; R 5 represents H, Cl or C 1-3 alkyl, and R 6 and R 7 independently represent H, F, Cl, Br, C 1-3 alkoxy, C 1-3 alkyl or C 1-3 acylamino may be produced by reacting an appropriate phenylhydrazine with a ketone of general formula wherein X = Cl or substituted amino. The novel pyrazolines exhibit optical brightening properties.
