by alkylation reactions under phase transfer catalysis conditions. The obtained compounds (4, 5 and 6) obtained were characterized using 1H- and 13C- NMR spectroscopy and X-ray. Their molecular and crystal structures have been determined by single-crystal X-ray diffraction techniques. The experimental data, were compared with the predicted ones spectral data were also obtained using density functional
摘要 在这项工作中,在相转移催化条件下通过烷基化反应合成了三种新型长链烷基取代的 1,4-苯并噻嗪衍生物。获得的化合物(4、5和6)使用1H-和13C-NMR光谱和X-射线表征。它们的分子和晶体结构已通过单晶 X 射线衍射技术确定。将实验数据与预测数据进行比较 光谱数据也是使用密度泛函理论 (DFT) 在 B3LYP/6-31G(d,p) 理论水平获得的。此外,通过 Hirshfeld 表面分析确定了化合物活性原子之间最密切的接触。根据蒙特卡罗模拟,新化合物可以作为铁的良好缓蚀剂和铜和铝金属的缓蚀剂。
