| titleOfInvention | A PROCEDURE FOR THE PREPARATION OF HYDRAZONES. |
| abstract | This invention relates to a method of preparing hydrazones of the formula R1R3 ANGLE N-N=C ANGLE (I) R2R4 in which R1 and R2, which may be identical or different, represent a linear alkyl radical of from 1 to 12 carbon atoms, a branched alkyl or cycloalkyl radical of from 3 to 12 carbon atoms, an aromatic radical of from 6 to 12 carbon atoms having a benzene or naphthalene nucleus, or a radical of from 5 to 12 carbon atoms having a pyridine nucleus, or R1 and R2 together form a linear or branched alkylene radical of from 3 to 12 carbon atoms in which one of the carbon atoms of the chain may be replaced by an oxygen atom, all of the above radicals being unsubstituted or substituted by one or more atoms or groups such as chlorine, bromine, fluorine, or iodine atoms or hydroxy, ether, carboxylic acid, carboxylic amide or ester, nitrile, nitro, or sulphonic acid or amide groups, or one of the two radicals R1 and R2 may be a hydrogen atom, and in which R3 and R4, which may be identical or different, represent a hydrogen atom, a linear alkyl or cycloalkyl radical of from 3 to 12 carbon atoms, in which one of the carbon atoms of the cycloalkyl radical may be replaced by an oxygen atom, or an aromatic hydrocarbon radical of from 6 to 12 carbon atoms or R3 and R4 together represent a linear or branched alkylene radical of from 3 to 11 carbon atoms, the above radicals being unsubstituted or substituted by atoms or groups such as chlorine, bromine, fluorine, ethylenic groups, nitro, hydroxy, alkoxy, or carboxylic acid or ester radicals , which comprises reacting a primary or secondary amine of the formula WHEREIN R1 and R2 are as defined above, ammonia, and a carbonyl compound of the formula WHEREIN R3 and R4 are as defined above, with a peroxide compound. |
