With mercury(II) acetate in dilute acetic acid no specifity of the oxime configuration is observed, and the nitrones and oxadiazines are produced together. This may be explained by a reaction with the acetate ion at the iminium oxime stage. NMR experiments in CDCl3 have shown that treatment of nitrone 2 and oxadiazine 3 with CF3COOD causes ring cleavage by prototropy and after longer reaction times generates
