used as the support for a palladium-containing (1 wt%) catalyst. The materials, analyzed by XRD and SEM techniques, were tested in the synthesis of some thionocarbamates from reaction of sodium O-isopropyl carbonodithioate with the corresponding amines. The best yield was obtained with 3 mmol% of the catalyst (Pd/Ti-HMS-10) in water as solvent after 10–15-h heating at 75 °C. The structures of the products
摘要制备具有不同Si / Ti比(5、10、20和30)的Ti-
HMS材料,并将其用作含
钯(1 wt%)催化剂的载体。通过XRD和
SEM技术分析了该材料,并通过O-异丙基碳二
硫代
硫酸钠与相应的胺反应合成了一些
硫代
氨基甲酸酯。在75°C加热10-15小时后,使用3 mmol%的催化剂(Pd / Ti-
HMS-10)在
水中作为溶剂可获得最佳产率。产物的结构通过光谱技术鉴定,例如1 H-NMR,13 C-NMR,IR和元素分析。 图形概要
