2,6-DICHLORO-4-(TRIFLUOROMETHYL)PHENYLHYDRAZINE

[2,6-Dichloro-4-(trifluoromethyl)phenyl]hydrazine may be used for the synthesis of pyrazolo[4,3-d]isoxazole derivatives. It may also be used in the synthesis of following N-(2,6-dichloro-4-trifluoromethyl)phenyl-N′-(1-phenylethylidene) hydrazines:

• N-(2,6-dichloro-4-trifluoromethyl)phenyl-N′-(1-phenylethylidene)hydrazine
• N-(2,6-Dichloro-4-trifluoromethyl)phenyl-N′-[1-(4-chlorophenyl)ethylidene]hydrazine
• N-(2,6-Dichloro-4-trifluoromethyl)phenyl-N′-[1-(3-chlorophenyl)ethylidene]hydrazine
• N-(2,6-Dichloro-4-trifluoromethyl)phenyl-N′-[1-(4-bromophenyl)-ethylidene]hydrazine
• N-(2,6-Dichloro-4-trifluoromethyl)phenyl-N′-[1-(3-bromophenyl)ethylidene]hydrazine
• N-(2,6-Dichloro-4-trifluoromethyl)phenyl-N′-[1-(4-methoxyphenyl)ethylidene]-hydrazine
• N-(2,6-Dichloro-4-trifluoromethyl)phenyl-N′-[1-(4-trifluoromethylphenyl)-ethylidene]hydrazine
• N-(2,6-Dichloro-4-trifluoromethyl)phenyl-N′-[1-(4-nitrophenyl)ethylidene]hydrazine
• N-(2,6-Dichloro-4-trifluoromethyl)phenyl-N′-[1-(6-methoxy-naphthalen-2-yl)-ethylidene]hydrazine

[2,6-Dichloro-4-(trifluoromethyl)phenyl]hydrazine is a hydrazine derivative. It reacts with excess of ethyl acetoacetate to afford 1-(2,6-dichloro-4-(trifluoromethyl)phenyl)-3,4-dimethylpyrano[2,3-c]pyrazol-6(1H)-one.
