Caesium thiosulphate

Caesium thiosulphate, Cs2S203.—The thiosulphate is formed on addition of sulphur to a boiling solution of the sulphite,16 and also by the action of the carbonate on barium thiosulphate.17 It crystallizes in small, very soluble needles. 

The electrical conductivities of soln. of a great many compounds in liquid hydrogen halides have been measured by E. H. Archibald and D. McIntosh. The conductivity is raised considerably by phosphoryl chloride. Sodium sodium sulphide, borate, phosphate, nitrate, thiosulphate, and arsenate chromic anhydride potassium nitrate, hydroxide, chromate, sulphide, bisulphate, and ferro- and ferri- cyanide ammonium fluoride and carbonate j rubidium and caesium chloride magnesium sulphate calcium fluoride ... 

Caesium tetrathionate, Cs2S406.—The tetrathionate is an intermediate product in the production of the trithionate by Mackenzie and Marshall s method,2 and is also formed by the action of iodine on the thiosulphate. ... 

Reaction of perfluoroisobutene with sulphur in the presence of caesium fluoride yields 2,4-bis(hexafluoroisopropylidene)-l,3-dithietan (bistrifluoro-methylthioketen dimer) together with the polysulphides (CF3)3C Sn-C(CF,), (n = 3 or 4). Bistrifluoromethylthioketen dimer is available by the reaction of a variety of sulphur nucleophiles, alkali-metal salts of thiocarbamates, thiocarbonates, thiocarboxylates, thiophosphates, thiosulphate, thiocyanate, hydrosulphide, etc. with perfluoroisobutene. - The reaction with...
