Preparation of α-ketocarboxylic acid N-acylamides |
| abstract |
α-Ketocarboxylic acid N-acylamides of the formula n n R.sup.1 --CO--CO--NH--CO--R.sup.2 n n in which n R 1 is an optionally substituted aliphatic radical with up to 12 carbon atoms, an optionally substituted cycloalkyl radical with 3 to 10 carbon atoms, an optionally substituted heterocyclic radical, and n R 2 is an optionally substituted aliphatic radical with up to 8 carbon atoms or an optionally substituted phenyl radical, n are prepared by reacting an acyl cyanide of the formula n n R.sup.1 --CO--CN n n with a carboxylic acid anhydride of the formula n n R.sup.2 --CO--O--CO--R.sup.2 n n in the presence of a strong acid, and then adding water to the reaction mixture. The products can be used directly in the synthesis of known herbicides. |
