A series of thirteen novel 2-aryl-3-phenyl-2,3-dihydro-4H-1,3-benzothiazin-4-ones was prepared at room temperature by T3P-mediated cyclization of N-phenyl-C-aryl imines with thiosalicylic acid. The spectroscopic and physical properties are reported and discussed. H-F and C-F couplings were observed in the NMR spectra of fluorinated compounds. Through-space interactions were observed in the H and C
通过T3P介导的N-苯基-C-芳基亚胺环化反应,在室温下制备了一系列13种新型2-芳基-3-苯基-2,3-二氢-4H-1,3-苯并噻嗪-4-酮类化合物。硫代水杨酸。报告和讨论了光谱和物理特性。在氟化化合物的 NMR 光谱中观察到 HF 和 CF 偶联。在邻硝基化合物的 H 和 C NMR 光谱中观察到空间相互作用。在邻/间/对硝基系列的 IR 和 UV 吸收中观察到趋势。
