Simple organic acids like 2,4‐dinitrobenzenesulfonic acid (DNBSA) catalyze the Ritter reaction of secondary benzylic alcohols giving rise to the corresponding N ‐benzylacetamides in usually high yields. Reactions can be conducted without exclusion of oxygen and without the need of dry solvents. With tertiary α,α‐dimethylbenzylic alcohols a different pathway involving a formal dimerization reaction takes place under the acid‐catalytic conditions used. (© Wiley‐VCH Verlag GmbH & Co.
