cyanoguanidine (CG) with formaldehyde, CG was first hydroxymethylated, then methoxylated, and finally exhaustively hydroxymethylated with a large excess of formaldehyde. 4-Cyanoimino-3-methoxymethylperhydro-1,3,5-oxadiazine was isolated as a major reaction product of 1,3-bis(methoxymethyl)-2-cyanoguanidine with formaldehyde. This product is an adduct of 3 mol of formaldehyde per mole of CG and a six-membered
