Reaction of dialkyl ketipinates with 2,4-dinitrophenylhydrazine
Reaction of (2Z,4Z)-3,4-dihydroxy-2,4-hexadiene-1,6-dioates (dialkylketipinates) with 2,4-dinitrophenylhydrazine is investigated, the (3Z)-3-[2-(2,4-dinitrophenyl)hydrazono]hexan-l,6-dioates and (3Z,4Z)-3,4-bis[2-(2,4-dinitrophenyl)hydrazono]hexan-l,6-dioates are prepared. The structure peculiarities of synthesized ethers are discussed. The structure of prepared compounds is proved by IR and NMR spectroscopy data.
