| abstract | 1,225,672. Oxalic acid diamides. CIBAGEIGY A.G. 14 March, 1968 [20 March, 1967], No. 20621/69. Divided out of 1,225,671. Heading C2C. The invention comprises compounds of the formula where R 1 is alkyl C 1-18 radical optionally sub stituted by one or more chlorine atoms, hydroxyl, alkoxy C 1-4 , carboxyl, nitrile, carboxylic acid amide or alkyl C 1-12 ester groups, alkenyl C 3-4 , optionally chlorinated or alkylated benzyl, aliphatic acyl C 2-18 , or optionally chlorinated or C 1-4 alkylated benzoyl radicals, X 1 is a hydrogen or halogen atom or an alkyl C 1-12 , a sulphonamido, nitrile, carboxylic acid alkyl C 1-4 ester, halogenoalkyl, sulphonic acid, phenyl or phenylalkyl C 7-10 , or two ortho-positioned X 1 residues together form a fused-on 6-membered aromatic carbon ring, m and n are each 1 or 2 and the sum m + n is at most 3; D 3 is a linear or branched, saturated alkyl C 1-18 which may be substituted by one or more hydroxyl, alkoxy C 1-8 , carboxyl, carboxylic acid ester groups containing 1 to 12 carbon atoms in the ester grouping, carboxylic acid amide groups, nitrile groups, sulphonic acid ester groups or morpholino groups, or is alkenyl C 3-4 , benzyl or cyclohexyl radical. They are prepared by reacting an oxalic acid semi-amide of the formula where Z is a hydroxy or alkoxy C 1-4 group or a halogen atom with an amine of formula D 3 NH 2 at a temperature of from 0-200 C. optionally in the presence of an inert solvent. The compounds act as stabilizers against ultra-violet radiation. Oxalic acid-N-(4-methoxy phenyl) semi-amide ethyl ester is prepared from p-anisidine and diethyl oxalate. |
