Polarographic determination of malononitrile.
A procedure is proposed for the determination of malononitrile by differential pulse polarography in methanolic 0.1M tetraethylammonium iodide/0.001M tetramethylammonium hydroxide as the supporting electrolyte. In this medium malononitrile is chemically converted into an electroactive species. With close control of timing of the steps in the procedure the error of the method is +/-1.5% in the c...
متن کامل2-(4-Nitrobenzylidene)malononitrile
In the title compound, C(10)H(5)N(3)O(2), the benzyl-idene-malono-nitrile unit is nearly planar, with a maximum deviation of 0.129 (2) Å for a terminal N atom; the nitro group is approximately coplanar with the benzene ring [dihedral angle = 8.8 (3)°]. An intra-molecular C-H⋯N hydrogen bond stabilizes the mol-ecular conformation.
متن کامل2-[4-(Benzyloxy)benzylidene]malononitrile
In the title mol-ecule, C(17)H(12)N(2)O, the dihedral angle between the two benzene rings is 84.98 (10)°. The dicyano-ethyl-ene group is coplanar with the benzene ring to which it is bonded. No classic hydrogen bonds were found in the crystal.
متن کاملMNDO Studies on Malononitrile Dimerization
As a starting reagent in organic synthesis, malononitr i le-dicyanomethylene has an established posit ion because of its reactivity in the addi t ion, self addi t ion, and condensation reactions leading to various carbocyclic and heterocyclic systems [1]. The a im of our work is to investigate the reaction path of malononitrile dimerizat ion and the structure of the reaction product using q u a...
متن کامل(E)-2-(1,3-Diphenylallylidene)malononitrile
The title compound, C(18)H(12)N(2), adopts an E conformation with the benzyl-idenemalononitrile and phenyl groups located on opposite sides of the C=C bond. The two phenyl rings are oriented at a dihedral angle of 62.49 (7)°.
