Thermal and mercuric ion

L. E. Overman, Thermal and mercuric ion catalyzed [3,3]-sigmatropic rearrangement of allylic trichloroacetimidates. 1,3-Transposition of alcohol and amine functions,. /. Am. Chem. Soc., 96 (1974) 597-599. 

Singh [1] has examined infra-red spectra of mercuric, silver and lead fulminates, and Beck [2] those of sodium and potassium fulminates. The maxima 2147 and 1225 cm-1 were found to be characteristic of asymmetric and symmetric vibrations of the O—N—C group, respectively. The maximum 1181 cm-1 was assigned to the bending frequency of the same group [1]. Beck also found that the transient formation of an isomeric ion eN=C—O can occur on thermal decomposition of fulminates.
