A facile and efficient two-step synthetic route to previously inaccessible 1,3-unsubstituted 2-imino-5-oxooctahydroimidazo[4,5-d]imidazol-1-ium iodides has been developed using easily accessible thioglycolurils, MeI, and various primary amines, morpholine, or ethylene diamine. The structure of representative products and hydrogen-bonding pattern in their crystals have been investigated by X-ray diffraction.Downloads
