Cyclic Imidocarbonate Hydrochlorides from the Reaction of Cyanogen Chloride with Dithiols and Diols

The Acid‐Catalysed Reaction of Cyanogen Chloride with Aliphatic Alcohols. A General Synthesis of Aliphatic Carbamates

“…The acid-catalysed reaction of alcohols with 1 may be rationalized in terms of an initial addition of HC1 to 1 with the formation of the very reactive electrophilic intermediate -10, which in the presence of the alcohol subsequently forms the alkyl imidocarbonate hydrochloride 2 via 11 releasing HC1. Similarly to the cyclic imidocarbonate hydrochlorides (11) , -12 decomposes under the reaction conditions into the corresponding carbamate 3 and the alkyl chloride 4. The steps (1) to ( 3 ) correspond to the mechanism already proposed by Addor (11) for the reaction of dithiols and diols with 1.…”

Photodegradation of Cytrolane (mephosfolan) systemic insecticide in the aquatic environment using carbon-13 as a mass tracer

“…The structure of this material was shown by infrared and nuclear magnetic resonance spectroscopy to be 2-(dichlorophosphinylimino)-5-methyl-l,3-dithiolane (Addor, 1964). Equimolar amounts of 2-imino-5-methyl-l,3-dithiolane hydrochloride and phosphorus oxychloride were refluxed approximately 3 h in toluene until the theoretical amount of hydrogen chloride was eliminated and most of the solids disappeared.…”
