Ueber die Lichtempfindlichkeit von Diazoverbindungen, besonders von 3‐Diazocarbazol, und einige neue Carbazolderivate

Abstract: Gelegentlicb einer Untersochung des Carbazols 5 4 9 1i:ibt.n wir daa 3-Amidocarbazol in grosseren Mengen geworincn uiid wurden durch die hervorragende Licbtempfiiidlichkeit von dessrll Diazorerbindung darauf gefiihrt, zu versuchen, es zur Erzengung photographischer Copien zu verwerthen. Das Diazocarbazol ist ans 3-Arnidncarbazol in der iiblicberr Weise leicbt zu erbalten und ziernlich besttindig. Es liefert, niit Phenolen und Aminen gekuppelt, substantive, Zuni Tbeil sehr lichtechte Farbstoffe, die sich ihrer … Show more

“…The yield of amine, which was used without purification, was (0.1 7 g, 50%). (13). Allylation of the above amino compound (0.15 g, 0.74 mmol) using allyl bromide and potassium carbonate in DMF (10 ml) as previously described for the unlabelled compound, gave the 'N-labelled 2-allylamino derivative (0.07 g, 40%) after chromatography.…”

“…It is only in recent times that many of the simple carbazole derivatives have been prepared, and a short account of them is therefore in order. 82,94), by the action of nitric acid on iV-nitrosocarbazole. The nitroso group is then readily removed by heating with alkali or glacial acetic acid.…”
