N,N'-Bis(salicylidene)-1,3-propanediamine 화학적 특성, 용도, 생산

화학적 성질
Light yellow to Yellow to Green powder to crystal
용도
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)
일반 설명
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. Found: C, 71.9; H, 6.45; N, 10.47%. λmax = 243 nm, ε = 7045 dm3 mol-1 cm-1 in DMSO, λmax = 242 nm, ε = 7865 dm3 mol-1 cm-1 in MeOH.
