  Synthese von N, N′-Äthylen-, N, N′-Tetramethylen-, N, N′- Hexamethylen- und C, C′-Dimethyl-N, N′-äthylen-bis-sydnon wird beschrieben. Einige der erhaltenen Bis-sydnone wurden in C, C′-Dihalogeno-N,N′-polymethylen-bis-sydnone übergeführt. Durch Zersetzung der Bis-sydnone mit Säuren erhielt man die entsprechenden aliphatischen Bis-hydrazine, die mit Benzaldehyd und Phtalaldehyd umgesetzt wurden.
