Flow me a Ritter: Ritterreactions are performed in a simple microreactor setup using tert‐butylacetate as versatile carbocation source. The protocol avoids the handling of large amounts of hot concentrated sulfuric acid as low concentrations are optimal for rapid access tert‐butyl‐ or diphenylmethyl‐protected amides.

as a reaction solvent facilitates the Ritterreaction between alcohols and nitriles. In(OTf)3 was found to be a viable catalyst for this transformation. The newly developed catalytic conditions for the Ritterreaction were successfully applied to the synthesis of various amides, which were formed in good to excellent yields. The catalytic activation of secondary alcohols for Ritterreactions in liquid
