1-[(6-Chloro-pyridin-3-yl)meth-yl]imidazolidin-2-iminium chloride
Abstract:
The title compound, C(9)H(12)ClN(4) (+)·Cl(-), is a natural metabolic product of imidacloprid [systematic name: (E)-1-(6-chloro-3-pyridyl-meth-yl)-N-nitro-imidazolidin-2-yl-idene-amine] and was obtained by the reduction of the latter using Fe in HCl. The dihedral angle between the pyridine and imidazole rings is 62.09 (12)°. The crystal structure is stabilized by N-H⋯Cl and C-H⋯Cl inter-actions involving the chloride anion. The pyridine N and the chloride atoms are not involved in inter-molecular inter-actions.

Alkyl Halides
Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...

Imines are formed under mildly acidic conditions. A pH of 4.5 is ideal for the reaction.
If the pH is low or the solution is too acidic, the reaction slows down in the...

In the first step of the aminolysis mechanism, the amine attacks the carbonyl carbon of the acyl chloride to form a tetrahedral intermediate. In the second step, the carbonyl group is re-formed with the elimination of a chloride...
