Heteroorganic Substances. IL. Reactions between N-morpholinosulfenylchloride and Ethane-alcoxy-thiophosphonous Acids and Ethane-ethyl-dithiophosphonic AcidThe syntheses of bis-(ethane-alkoxy-thiophosphonyl)-monosulfides 3a-c and bis-ethane-ethoxy-thiophosphonyl)-trisulfide 5 are described. It is established, that the reaction path depends on the acidity of the starting compounds. In the first case (pK ∼ 7 the reactions between ethane-alkoxy-thiophosphonous acids and morpholinosulfenylchloride are three-step reactions, the intermediates being the unknown S-morpholino-ethane-alkoxy-dithiophosphonates 1a-c as well as the sulfenylchlorides of ethane-alkoxy-thiophosphonic acid 2a-c. In the second case (pK ∼ 3) a fourth reaction has to been taken into account. The intermediate sulfenamide derivatives are isolated and characterised. The sulfenylchlorides derivatives could not been isolated; their presence was indirectly demonstrated by chemical reactions.
