theory (TD-DFT) at B3LYP/6-31G and B3LYP/6-311G(d,p) levels of theory. From the energies of frontier molecular orbitals (HOMO–LUMO), the reactivity descriptors, such as chemical potential (μ), hardness (η), softness (S), electronegativity (χ) and electrophilicity index (ω) have been calculated. The energetic behavior of the investigated compounds (1 and 2) has been examined in gas phase and solvent media
合成了两种具有三齿腙基配体(2-乙酰基噻唑的缩合产物)的新型 Zn(II) 配合物,并通过红外 (IR) 和核磁共振 (NMR) 光谱以及单晶 X 射线衍射方法对其进行了表征。配合物 1、2 和最近合成的 [ZnL3(NCS)2] (L3 = (E)-N,N,N-trimethyl-2-oxo-2-(2-(1-(pyridin-2-yl)ethylidene) )肼基)乙-1-胺)配合物3作为酮-胺-炔(KA2)偶联反应的潜在催化剂进行了测试。已在密度泛函理论 (DFT)/B3LYP/6-31G 理论水平计算了新合成和表征的 Zn(II) 配合物的气相几何优化,而最高占据分子轨道和最低未占据分子轨道(HOMO 和 LUMO)能量是在 B3LYP/6-31G 和 B3LYP/6-311G(d,p) 水平的瞬态密度泛函理论 (TD-DFT) 内计算的的理论。从前沿分子轨道(HOMO-LUMO)
