| | N,N'-Bis(salicylidene)-1,3-propanediamine Usage And Synthesis |
| Chemical Properties | Light yellow to Yellow to Green powder to crystal
| | Uses | N,N′-Bis(salicylidene)-1,3-propanediamine has been used in the synthesis of:
- new trinuclear heterometallic Cu(II)-Mn(II) complexes
- mononuclear nickel complex, NiL (LH2 = N,N′-bis(salicylidene)-1,3-diaminopropane)
| | Application | N, N'-bis(salicylidene)-1,3-propane diamine (SB-Salpr) could prepare a new Al3+ carbon paste ion selective electrode to quantify trace Aluminum. The bi-thioglycolate functionalized salpn linker could be further transformed into Cu-ICP nanoparticles. This linker could be synthesized through the functionalization of salpn (salpn = N, N'-Bis(salicylidene)-1,3-propanediamine) ligand with sodium thioglycolate[1–2]. | | General Description | N,N′-Bis(salicylidene)-1,3-propanediamine is a di-Schiff base ligand. | | Synthesis | N,N'-Bis(salicylidene)-1,3-propanediamine is prepared by the reaction of 2-Hydroxybenzaldehyde and 1,3-diaminopropane. The specific synthesis steps are as follows:
General procedure: This Schiff base was prepared via a condensation reaction in EtOH under hydrothermal conditions using 2-hydroxy-benzaldehyde and 1,3-diaminopropane. 2-Hydroxy-benzaldehyde (0.02 mol, 2.44 g) was dissolved in 40 cm3 of warm EtOH, then 0.01 mol (0.74 g) of 1,3-diaminopropane was added to this solution and heated up to the boiling point. After cooling, yellow crystals were filtered and air-dried. Yield: 92-95%, mp 58 °C (determined by TG). Elemental Anal. Calc. for C17H18N2O2: C, 72.3; H, 6.43; N, 9.92.
