Neue hochmolekulare substanzen aus isocyanaten mit funktionellen gruppen

Abstract: Organische Isocyanate, die neben der NCO‐Gruppe eine Sulfenchlorid‐, Alkoxy‐methyl‐ oder Azidgruppe im Molekül enthalten, wurden nach neuen Verfahren her‐gestellt. Ihre Umsetzung mit reaktiven hochmolekularen Stoffen liefert Kunst‐stoffe oder Kunststoffzwischenprodukte mit technisch interessanten Eigenschaften. Isocyanate mit einer Sulfenchloridgruppe, z. B. 4‐Isocyanatophenylsulfenchlorid, lagern sich an fast alle ungesättigten organischen Verbindungen zu neuen Mono‐oder Polyisocyanaten an. Aus ungesättigten … Show more

“…The synthesis of this compound was previously reported in the literature, but with another synthetic strategy. 45 In a reactor, 4-azidoaniline hydrochloride (0.410 g, 2.40 mmol) was dissolved in anhydrous THF (16 mL). Triphosgene (0.713 g, 2.403 mmol) was dissolved in anhydrous THF (16 mL) and injected into the reactor.…”

“…This is consistent with the exclusive formation of trimer from the chloromethyl methyl ether and sodium cyanate reaction in DMF. 3 The decomposition of dioxazolone 3 in refluxing xylene (140°) was also investigated. After 16 hr, most of the dioxazolone 3 remained unreacted; however, a weak isocyanate band had developed at 2250 cm-1.…”
