Harnessing hydrazoic acid in flow! 2‐Oxazolines can be ring‐opened in a very efficient manner by treatment with in situ generated hydrazoic acid. Despite the toxic and explosive nature of hydrazoic acid, this process can be conducted safely in a continuous‐flow format with residence times as short as 5 min at 130 °C (see scheme).
