All four cyanogen halides are known. The fluoride is a gas at ordinary temperatures and is prepared by pyrolysis of (FCN)3 which in turn is made from (ClChOa and NaF in tetramethylene sulphone. The chloride is a liquid boiling at 14-5°C which readily polymerizes to cyanuric chloride, CI3C3N3, and is prepared by the action of chlorine on metal cyanides or HCN. The bromide and iodide, also prepared from halogens and alkali cyanides, form colourless crystals. All four halides have been studied in the vapour state and all except FCN also in the crystalline state (Table 21.9). 

The relative yields of isothiazoles and dithiins depend on the nature of the groups R1 and R2. Whilst with most 3-(methylsulfanyl)-l,4,2-dithiazines the main products are isothiazoles and sulfur, thermolysis of 3-(methylsu1fanyl)-5,6-trimethylene-l,4,2-dithiazine affords the dithiin and methyl rhodanide as the main products, another example is 5,6-tetramethylene-l,4,2-dithiazine, which gives the dithiin together with hydrogen cyanide.2... 

The iminoether 9 was prepared according to the procedure of Nohira et al. (9) in which tetramethylene chlorohydrin, potassium cyanide, glycerol and water were heated at 100-110 C to give the cyanohydrin. The hydrochloride salt of the imino ether was formed by passing HCl gas into the ether solution of...
