甲基 吗啉-4-碳二硫代酸酯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a stirred solution of morpholine (201 mL, 2295 mmol) in water (2 L) was added carbon disulfide (0.138 L, 2295.67 mmol) under nitrogen. Sodium hydroxide (96 g, 2410 mmol in solution in 1 L of water) was then added dropwise. The resulting mixture was stirred at room temperature for 1 h, then cooled to 5° C. with an ice bath and dimethyl sulphate (217 mL, 2295 mmol) was added dropwise. The mixture was stirred 1 h at room temperature, the obtained solid was collected by filtration, washed with water (2×1 L) and dried under vacuum over phosphorus pentoxide at 50° C. to give methyl morpholine-4-carbodithioate (360 g, 88%). Proton NMR Spectrum: (CDCl3): 2.68 (s, 3H), 3.71-3.84 (m, 4H), 4.02 (bs, 2H), 4.30 (bs, 2H). cooled to 5° C. with an ice bath The mixture was stirred 1 h at room temperature the obtained solid was collected by filtration washed with water (2×1 L) dried under vacuum over phosphorus pentoxide at 50° C.
