experimental part, p. 430 - 436 (2009/07/19)
Reactions between various benzyl alcohols or tert-butyl alcohol and nitriles were carried out in the presence of catalytic amounts (usually 10-20 mol-%) of o-benzenedisulfonimide as a Bronsted acid catalyst; the reaction conditions were mild and the yields of amides were good. The catalyst was easily recovered and purified, ready to be used in further reactions, with economic and ecological advantages. Wiley-VCH Verlag GmbH & Co. KGaA, 2009.

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. KGaA, 2007.
Iron(III) perchlorate - A novel reagent in synthesis
Kumar, Baldev,Kumar, Harish,Singh, N
, p. 460 - 461 (2007/10/02)
Iron (III) perchlorate in acetonitrile as the solvent converts alkohols and alkyl halides to acetamide derivatives, cleaves glycols and converts α-hydroxy acids to aldehydes or ketones.
