Improvements in the object of the main patent, no. 239,298, by "Process for the preparation of new heterocyclic nitrogen compounds", particularly for the preparation of saturated 2-imino-1,3-di-N-heterocyclics of general formula I ** (See formula) ** where does it mean R1 a lipophilic radical, R2 hydrogen, or a low molecular weight alkyl radical, and To a hydrocarbon radical linked to carbon atoms - alpha, beta or -alpha, gamma with both nitrogen atoms, characterized in that a heterocyclic compound of general formula II is transposed ** (See formula) ** in which A presents the previous significance and R2 means hydrogen, or an alkyl radical of low molecular weight, with the approximately stoichiometric amount of a medium introducing a lipophilic radical of at least 10 carbon atoms and, optionally, also with the approximately stoichiometric amount of a medium introducing a low molecular weight alkyl group.
