Die Hydroazidierung nichtaktivierter Alkine beschreiben X. Bi et al. in ihrer Zuschrift auf S. 5409 ff. Ethinylcarbinole wurden durch Silberkatalyse chemo‐ und regioselektiv zu Vinylaziden umgesetzt, und eine Vielzahl von 2‐Azidoallylalkoholen konnte in guten bis exzellenten Ausbeuten erhalten werden. Der präparative Nutzen dieser Verbindungen wurde durch ihre weitere Umsetzung zu NH‐Aziridinen verdeutlicht.
The hydroazidation of alkynes is the most straightforward pathway to synthetically useful vinyl azides. However, a general hydroazidation of alkynes remains elusive. Herein, a chemo‐ and regioselective transformation of ethynyl carbinols into vinyl azides is described. This reaction produces a wide variety of 2‐azidoallyl alcohols with high efficiency and in good to excellent yields. These compounds...
