And the article was included in Synthesis and Reactivity in Inorganic and Metal-Organic Chemistry in 1997.Application In Synthesis of 3,3′,3”-Nitrilotripropanenitrile This article mentions the following:
Four binuclear Cd(II) macrocyclic complexes were synthesized by [2+2] Schiff base condensation of tris(3-aminopropyl)amine (trpn) with sodium 2,6-diformyl-4-R-phenolate (R = CH3, L1; R = CH3O, L2; R = Br, L3; R = Cl, L4) in the presence of Cd(ClO4)2·6H2O. The crystal structure of [Cd2L2](ClO4)2·0.5MeOH was determined by x-ray diffraction. The crystal is triclinic, space group P1̅, a 10.455(6), b 11.451(4), c 20.130(6) Å, Z = 2, α 105.75(3), β 82.84(3), γ 97.21(3)°, R = 0.052, Rw = 0.064. The crystal structure, spectral characterization and molar conductivity show that two Cd(II) ions are bridged by two μ2-phenoxy O atoms. Each Cd(II) atom is located in a N4O2 coordination environment. The coordination geometry around the Cd(II) is a distorted octahedron. In the experiment, the researchers used many compounds, for example, 3,3′,3”-Nitrilotripropanenitrile (cas: 7528-78-1Application In Synthesis of 3,3′,3”-Nitrilotripropanenitrile).
3,3′,3”-Nitrilotripropanenitrile (cas: 7528-78-1) belongs to nitriles. Nitrile carbon shifts are in the range of 115–125 ppm whereas in isonitriles the shifts are around 155–165 ppm. Alkyl nitriles are sufficiently acidic to undergo deprotonation of the C-H bond adjacent to the CN group.Strong bases are required, such as lithium diisopropylamide and butyl lithium. The product is referred to as a nitrile anion. Application In Synthesis of 3,3′,3”-Nitrilotripropanenitrile
