Systematic studies on the behavior of 1,4,2-dithiazolium cations (1) toward various amino compounds (ammonia, aliphatic and aromatic amines, hydrazine, semicarbazide, thiosemicarbazide derivatives, etc.) were performed. The reaction pathway could be classified into three types depending on possible three fission modes of the initially-formed adduct. The main products were 5-imino-1,4,2-dithiazole,

A method for detecting and measuring a metal ion in an aqueous medium includes derivatizing a solid phase extraction material with a reactive material that undergoes a chemical reaction when contacted with the metal ion. The solid phase extraction material and the reactive material are positioned in an aqueous medium containing the metal ion, such that the metal ion contacts the reactive material and causes it to chemically react. The reaction of the reactive material is detected by optical spectroscopy to detect and measure the metal ion.
