反応手順
To a stirred mixture of 4.0 g (0.028 mol) O,S-dimethyl phosphoramidothioate, 2.2 g pyridine (0.028 mol) and 15 ml of anhydrous methylene chloride, chilled to 0°-5° C., was added dropwise 6.0 g (0.028 mol) propyl (chlorosulfenyl)(isopropyl)carbamate over a period of 15 minutes. Pyridine hydrochloride forms immediately during addition of the sulfenyl chloride. The reaction mixture was stirred for an additional half hour at room temperature after the addition of the sulfenyl chloride.
