  The green and highly selective reactions of aromatic aldehydes, malononitrile, and 2-(1-arylethylidene)malononitriles in ionic liquid of [bmim+]Br- at 50 degrees C unexpectedly gave 2-((E)-1,3-diarylallylidene)malononitriles. The modification of the reaction used 10mol% malononitrile as catalyst at 90 degrees C in [bmim+][[image omitted]]. A possible reaction mechanism for the formation of the product was proposed based on further experimental results. 2-((E)-1,3-Diarylallylidene)malononitriles were not detected at all in the designed reaction of aromatic aldehyde and 2-(1-arylethylidene)malononitriles at the same reaction conditions.

  The 2-((E)-3-(2-nitrophenyl)-1-(4-methoxyphenyl)allylidene)malononitrile and 2-((E)-3-(2-chlorophenyl)-1-(4-bromophenyl)allylidene)malononitrile were synthesized and characterized by IR, 1H NMR, and elemental analysis. The molecular structures were further confirmed by X-ray diffraction analysis. The former 1, C19H13N3O3, is triclinic, space group P−1, a = 7.3834(13), b = 10.901(3), c = 11.227(2) Å, α = 88.64(2), β = 71.596(14), γ = 78.186(18), Z = 2, V = 838.5(3) Å3. The unclassical hydrogen bond of C–H⋯N links the molecules forming polymers. The latter 2, C36H20Br2Cl2N4, is orthorhombic, space group Pnma, a = 20.900 (4), b = 7.0710 (11), c = 10.9170 (18) Å, Z = 2, V = 1613.4(5) Å3. The same hydrogen bond of C–H⋯N and another type of C–H⋯Cl hydrogen bond link the adjacent molecules forming polymers along a axis. The 2-((E)-3-(2-nitrophenyl)-1-(4-methoxyphenyl)allylidene)malononitrile and 2-((E)-3-(2-chlorophenyl)-1-(4-bromophenyl)allylidene)malononitrile were synthesized and characterized by IR, 1H NMR and elemental analysis.
