Die aus monosubstituierten Hydrazinen mit Dimedon erhaltenen Enhydrazine ergaben mitfreiem Amin und wäßriger Formaldehydlösung in keinem Fall faßbare Aminomethylprodukte. Erst die Umsetzung mit Methyleniminiumsalzen in Acetonitril führte zu Salzen der Mannichbasen.

attempted synthesis of a tetrahydroindazolone analogue, we report here an unexpected 1,5-nitrogen to carbon tosyl migration, resulting in the isolation of an unusual sulfonated dimedone. Synthetic and mechanistic investigations provide early insight into the scope of this reaction, with two potential mechanisms proposed.
