Non-metallic inorganic (iso) thiocyanates are usually prepared by allowing the corresponding halides, oxy-halides or thio-halides to react with silver, lead or mercury (I1) thiocyanate in some inert organic solvent. Since long refluxing of the components is required due to the fact that the heavy metal thiocyanates are insoluble, extensive decomposition often occurs and yields of the desired (iso) thiocyanates are relatively small. In a ...
