activation for this reaction. The benzamides were directly formed from alcohols and amine hydrochloride salts in short reaction times with yields up to 84 % and TOFs (turnover frequencies) up to 33.6 h–1. Among the examined transition metals, only nontoxic and inexpensive FeCl2·4H2O together with caffeine as a stabilizing ligand provided a uniquely efficient catalyticsystem for the transformation.

Magnetite-sulfonic acid (Nanocat-Fe-OSO3H), prepared by the wet-impregnation method, serves as a magnetically retrievable sustainable catalyst for the Ritter and multicomponent reactions. The as synthesized catalyst can be used in several reaction cycles without any loss of activity.

A pharmaceutical composition for the prophylaxis and/or treatment of diseases induced, exacerbated or reignited by stressors comprising the compound of formula (I)
wherein all symbols have the same meanings as described in the specification, etc. as an active ingredient.
A convenient and user-friendly method to yield benzamides from primary and secondary amines and various benzylic alcohols in the presence of a cheap iron salt (FeCl2 center dot 4H(2)O) and tert-butylhydroperoxide (70% in water) as a stoichiometric oxidant is described. Control experiments indicated that this reaction might involve radical species. This method proved to be general, generating a family of 30 benzamides and was applied to the preparative synthesis of anti-anxiety drug moclobemide. (C) 2014 Published by Elsevier Ltd.
