REACTIONS OF DICHLOROMETHANE WITH THIOANIONS. 3. PREPARATION AND AMINOLYSIS OF BIS(ALKOXYTHIOCARBONYLTHIO)METHANES

Abstract

Bis(alkoxythiocarbonylthio)methanes are prepared by reaction of sodium O-alkyldithiocarbonates in water with dichloromethane catalyzed by polyethylenglycol 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.

Key Words:

• Dichloromethane double substitution
• bis(alkoxythiocarbonylthio) methanes
• 5-alkyl-1,3,5-dithiazinanes
• polyethyleneglycol as catalyst
