Potassium thiocyanate is a chemical compound that contains potassium, sulfur, carbon, and nitrogen atoms with the formula KSCN. To 145.5 gm (1.5 moles) of potassium thiocyanate dispersed in 340 ml of ethanol heated to reflux, 235 gm (1 mole) of undecyl bromide are added gradually. These are colourless pleasant-smelling liquids that are readily hydrolysed by water. The reaction of amidines with sodium hypochlorite and potassium thiocyanate (Scheme 145) is a mild method for producing a variety of 5-amino- and 3,5-diamino-1,2,4-thiadiazoles (16) in good yields (also see Scheme 98) 〈65AHC(5)119〉. The level of protection provided by potassium thiocyanate extract or inactivated toxin vaccines may be improved by including cholera toxin, which strengthens the mucosal immune response, or by alginate encapsulation, which may enhance antigen presentation to macrophages (Jarvinen et al., 2000; Suckow et al., 1996, 1996a, 2002). The density of Thiocyanate is 1.89 grams per cubic centimeter. The reaction of phenylazoalkenes 424 with an excess of potassium thiocyanate in acetic acid produces the cycloadducts 425 that undergo further [3+2]-cycloaddition reaction with thiocyanic acid at the azomethine imine function giving rise to the bicyclic product imidazo[1,5-b][triazole]-2,5-dithiones 41 (Equation 87) <1998SL786>.
