Description
Verfahren zur Herstellung organischer Basen Die Patentschriften 427 858 und 455 585 beschreiben ein Verfahren zur Einführung von Stickstoff in organische Verbindungen mit Doppelbindungen,* welches darauf beruht, daB der unter Einwirkung von Katalysatoren auf Stickstoffwasserstoffsäure entstehende Iminrest- NIE derartig mit aromatischer Kohlenstoffdoppelbindung reagiert, daB sich der Iminrest unter Bildung von Aminen anlagert nach dem Schema . Es wurde nun gefunden, daß ungesättigte Verbindungen, seien es offene Ketten oder ringförmige Gebilde, mit dem Iminrest anders reagieren, und zwar derart, daß sich an der Stelle der Doppelbindung Stickstoff in die Kette oder den Ring ein-. schiebt.

It has now been found that unsaturated compounds, be they open chains or ring-shaped structures, react differently with the imine radical, namely in such a way that nitrogen is incorporated into the chain or ring at the point of the double bond. pushes. In this way, the well-known Schiff bases are formed from acyclic unsaturated compounds according to the scheme R, R1 and R2 are hydrogen or any organic radicals.
Ringförmige ungesättigte Verbindungen reagieren in analoger Weise mit dem Iminrest unter Ringerweiterung (Einschieben von Stickstoff in der Regel an der Stelle der Doppelbindung) nach dem Schema Die hierbei entstehenden heterocyclischen Verbindungen enthalten eine Doppelbindung im Ring, und zwar in der Regel zwischen Stickstoff und Kohlenstoff, doch ist auch eine nachträgliche Verschiebung der Doppelbindung möglich.Ring-shaped unsaturated compounds react in an analogous manner with the imine residue with ring expansion (insertion of nitrogen usually at the point of the double bond) according to the scheme The resulting heterocyclic compounds contain a double bond in the ring, usually between nitrogen and carbon, but a subsequent shift of the double bond is also possible.
