- REACTIONS 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
-
The 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. - Key words: 5-Alkyl-1,3,5-dithiazinanes; 3,5-dialkyl-1,3,5-thiadiazinanes; dichloromethane double substitution; polyethyleneglycol as catalyst

- Synthesis of Thiocarbonyl and Heterocyclic Compounds from 2-Methylene-1,3-dithietanes
-
2-Methyl-1,3-dithietanes bearing electron withdrawing groups on the methylene carbon atom were synthesized and their reactivities were studied.These compounds readily underwent a ring-opening reaction with a variety of nucleophilic reagents such as amines
