- ItemReactions of dichloromethane with thioanions .2. Formation of 5-alkyl-1,3,5-dithiazinanes, 3,5-dialkyl-1,3,5-thiadiazinanes, and 1,3,5-trialkyl-1,3,5-triazinanes by reaction of dichloromethane with sodium sulfide and monoalkylamines(GORDON BREACH SCI PUBL LTD, 1995) Torres, M; Vega, JCThe reaction of dichloromethane with sodium sulfide and monoalkylamines, catalyzed by polyethyleneglycol 1,500, is studied. A mixture of 5-alkyl-1,3,5-dithiazinane, 3,5-dialkyl-1,3,5-thiadiazinane, and 1,3,5-trialkyl-1,3,5-triazinane is obtained. The proportion of these heterocycles depends on the amine structure and the presence of sodium hydroxide.
- ItemReactions of dichloromethane with thioanions .3. Preparation and aminolysis of bis(alkoxythiocarbonylthio)methanes(1996) Benavente, C; Diaz, P; Vega, JCBis(alkoxythiocarbonylthio)methanes are prepared by reaction of sodium O-alkyldithiocarbonates in water with dichloromethane catalyzed by polyethylenolycol 1,500. The aminolysis of these products with monoalkylamines, in 1:7 molar proportion, in the presence of CH2Cl2 and the polymer above, affords 5-alkyl-1,3,5-dithiazinane, and dialkylcarbamothioate, in 1:2 molar proportion.
