Selective carboxylic acid decarboxylation was elaborated. Generation of acyltrifluoroacetyl peroxides from carboxylic peracids and trifluoroacetyl anhydride (Method A), as well as from trifluoroperacetic acid and acyltrifluoroacetyl anhydride (Method B), leads to simultaneous peroxide decomposition into the corresponding alkyltrifluoroacetates. DFT computations, as well as experimental data, support an acid-catalyzed heterolytic mechanism for acyltrifluoroacetyl peroxide decomposition. (C) 2002 Elsevier Science Ltd. All rights reserved.

synthetically important, environmentally benign hydrogenation of esters to alcohols has been accomplished in recent years only with precious‐metal‐based catalysts. Here we present the first iron‐catalyzedhydrogenation of esters to the corresponding alcohols, proceeding selectively and efficiently in the presence of an ironpincer catalyst under remarkably mild conditions.
