2-[4-(4,5-Dihydro-1H-imidazol-2-yl)phenyl]-4,5-dihydro-1H-imidazol-3-ium 4-aminobenzoate
In the cation of the title compound, C(12)H(15)N(4) (+)·C(7)H(6)NO(2) (-), the benzene ring makes dihedral angles of 30.51 (9) and 25.64 (9)° with the imidazole and imidazolinium rings, respectively. In the crystal, inter-molecular N-H⋯O and N-H⋯N hydrogen-bonding inter-actions link the mol-ecules into a three-dimensional network.

In the mol-ecule of the title compound, C(8)H(9)N(3), a new imidazoline derivative, the six- and five-membered rings are slightly twisted away from each other, forming a dihedral angle of 7.96 (15)°. In the crystal structure, neighbouring mol-ecules are linked together by inter-molecular N-H⋯N hydrogen bonds into extended one-dimensional chains along the a axis. The pyridine N atom is in close ...

The asymmetric unit of the title compound, C(12)H(14)N(4)·2C(6)H(7)NO(3)S·2H(2)O, contains one half of a centrosymmetric 1,4-bis-(4,5-dihydro-1H-imidazol-2-yl)benzene (bib) molecule, one 4-amino-benzene-sulfonic acid molecule and one water mol-ecule. In the bib molecule, the imidazole ring adopts an envelope conformation. The benzene rings of bib and 4-aminobenzenesulfonic acid are oriented at ...

In the title herbicideh/phytocide, known as imaza-pic, C(14)H(17)N(3)O(3), the pyridine and imidazole rings are almost coplanar [dihedral angle = 3.08 (5)°]. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, an N-H⋯O hydrogen bond links mol-ecules into a chain parallel to [010].
متن کاملThe pseudo-Michael reaction of 1-aryl-4,5-dihydro-1H-imidazol-2-amines with ethyl ethoxymethylenecyanoacetate
ABSTRACT The pseudo-Michael reaction of 1-aryl-4,5-dihydro-1H-imidazol-2-amines with ethyl 2-cyano-3-methoxyprop-2-enoate (ethyl ethoxymethylenecyanoacetate) is investigated. At -10 °C reaction takes place on the exocyclic nitrogen atom, giving exclusively ethyl esters of 2-cyano-3-[(1-phenyl-4,5-dihydro-1H-imidazol-2-yl)amino]prop-2-enoic acid. The formation of isomeric enamines which may be a...
