摘要 NEW MATERIAL: A hydrazine derivative of formula I or II (where R=H, CHO, COR', COOR', CONH
2 ; R' = a 1-4C alkyl, benzyl, phenyl) or a salt of a compd. of formula II (where R=H) and an org. or inorg. acid.
EXAMPLE: 1-[2-(2,4-Dichlorophenyl)pentylidene]-2-acetylhydrazine.
USE: A synthesis intermediate of 1-[2-(2,4-dichlorophenyl) pentyl]-1H-1,2,4-triazole useful as an bactericide.
PROCESS: A compd. of formula I is obtd. by reacting 2-(2,4-dichlorophenyl)- valeronitrile with a hydrazine of formula III under the existence of H, an acid and a catalyst for hydrogenation. A compd. of formula II is obtd. by catalytically hydrogenating a compd. of formula I.
