A new, fast and easy strategy for one-pot synthesis of full substituted cyclopropanes: direct transformation of aldehydes to 3-aryl-1,1,2,2-tetracyanocyclopropanes was written by Pesyan, Nader Noroozi;Kimia, Mohammad Ali;Jalilzadeh, Mohammad;Sahin, Ertan.

A new, fast and easy method for a one-pot reaction of aromatic aldehydes and dialdehydes with malononitrile and cyanogen bromide was developed to afford substituted 3-arylcyclopropane-1,1,2,2-tetracarbonitrile derivatives in excellent yield in a very short time (about 5 s). The product structures were characterized by IR, 1H-NMR, 13C-NMR, mass spectrometry and X-ray crystallog. techniques. For these compounds the crystallog. data showed two structures in a mirror image in solid case and one distinct structure in solution A reaction mechanism was discussed, whereby the synthesis of the target compounds was achieved by the formation of triethylammonium bromodicyanomethanide (I) as a key intermediate. The title compounds thus formed included 3-(2-nitrophenyl)-1,1,2,2-cyclopropanetetracarbonitrile (II) and related substances, such as a naphthalene, pyridine, furan and anthracene derivative A reaction of 1,4-benzenedicarboxaldehyde provided a dimer-type compound [3,3′-(1,4-phenylene)bis[1,1,2,2-cyclopropanetetracarbonitrile]]. In the experiment, the researchers used many compounds, for example, 2-(Anthracen-9-ylmethylene)malononitrile (cas: 55490-87-4Recommanded Product: 55490-87-4).
2-(Anthracen-9-ylmethylene)malononitrile (cas: 55490-87-4) belongs to nitriles. Nitrile carbon shifts are in the range of 115閳?25 ppm whereas in isonitriles the shifts are around 155閳?65 ppm. Nitrile groups in organic compounds can undergo a variety of reactions depending on the reactants or conditions. A nitrile group can be hydrolyzed, reduced, or ejected from a molecule as a cyanide ion.Recommanded Product: 55490-87-4
