The reaction of diazoisobutane with cyanic acid has been reported to give butyl cyanate in low yield (4%) . When treated with silver cyanate (equation (19)) , isopropyl iodide and sec-butyl iodide give a mixture of cyanate and isocyanate, although the yields show that this method is salt. Cyanates are organic compounds containing -OCN groups. Figure 12.10 shows the thermal ring trimerization of phenyl cyanate 83 to 2,4,6-triphenoxy-1,3,5-triazine 84. The final route to organic cyanates discussed in chapter 5.30.1.5 of COFGT (1995) uses cyanic acid or its metal salts to convert organic halides or diazoalkanes to cyanate functionality. Therefore, HOCN, NaOCN, and AgOCN have all been applied in the reaction with iodopropane, -butane, and 1-chloropentane. In either chemical reaction, urea is broken down into cyanic acid and ammonia, and then the cyanic acid is condensed to form melamine.
