(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
简单的有机酸如 2,4-二硝基苯磺酸 (DNBSA) 催化仲苄醇的 Ritter 反应,通常以高产率生成相应的 N-苄基乙酰胺。反应可以在不排除氧气和不需要干燥溶剂的情况下进行。对于叔 α,α-二甲基苄醇,在所使用的酸催化条件下发生了涉及正式二聚反应的不同途径。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
