An investigation of reactions involving N″-cyanoguanidine (CG) and its methyl derivatives with formaldehyde as well as the consideration of the molecular structures of CG and 4-cyanoimino-3-(methoxymethyl)perhydro-1,3,5-oxadiazine elucidated the formation pathway of the latter compound from CG: CG → N-hydroxymethyl N″-cyanoguanidine → N,N′-bis(hydroxymethyl)-N″-cyanoguanidine → 4-(cyanoimino)perhydro-1,3,5-oxadiazine → 4-cyanoimino-3-(hydroxymethyl)perhydro-1,3,5-oxadiazine → 4-cyanoimino-3-(methoxymethyl)perhydro-1,3,5-oxadiazine.
