1-(But-2-enylidene)-2-(2-nitrophenyl)hydrazine

1-(But-2-enyl­idene)-2-(2-nitro­phen­yl)hydrazine

The mol-ecule of the title Schiff base compound, C(10)H(11)N(3)O(2), adopts an E geometry with respect to the C=N double bond. The mol-ecule is roughly planar, with the largest deviation from the mean plane being 0.111 (2) Å, The enyl-idene-hydrazine group is, however, slightly twisted with respect to the phenyl ring, making a dihedral angle of 6.5 (3)°. An intra-molecular N-H⋯O hydrogen bond m...

Synthesis of 1-Hydroxy-2-(Prop-2'-Enyl) 9-Antrone

An efficient synthesis of the 1-hydroxy-2-(prop-2'-enyl)9-anthrone is described. Selective nitration of anthraquinone, reduction to the corresponding amine, diazotization and treatment by sulfuric acid solution afforded the 1-hydroxy-9,10-anthraquinone in good yield as the key intermediate. Reaction with allyl bromide/K2CO3 and subsequent selective reduction accompanie...

1-[4-(2-Fur­yl)but-3-en-2-yl­idene]-2-(2-nitro­phen­yl)hydrazine

In the title Schiff base compound, C(14)H(13)N(3)O(3), the furan and benzene rings are oriented at a dihedral angle of 10.24 (13)°. Intra-molecular N-H⋯O hydrogen bonding is observed between the imino and nitro groups.
