Acid/base-catalyzed ester hydrolysis in near-critical water
Lesutis, Heather P.,Glaeser, Roger,Liotta, Charles L.,Eckert, Charles A.

Hydrolyses of substituted benzoic acid esters in near-critical water (250-300°C) show autocatalytic kinetic behavior and surprisingly give the same rate constant regardless of substituent, suggesting that an acid-catalyzed mechanism predominates under our reaction conditions.

A one-pot, three-step protocol for the preparation of Grignard reagents from organobromides in a ball mill and their subsequent reactions with gaseous carbon dioxide (CO2) or sodium methyl carbonate providing aryl and alkyl carboxylic acids in up to 82 % yield is reported. Noteworthy are the short reaction times and the significantly reduced solvent amounts [2.0 equiv. for liquid assisted grinding (LAG) conditions]. Unexpectedly, aryl bromides with methoxy substituents lead to symmetric ketones as major products.

The oxidation of primary alcohols and aldehydes to the corresponding carboxylic acids is a fundamental reaction in organic synthesis. In this paper, we report a new chemoselective process for the oxidation of primary alcohols and aldehydes. This metal-free reaction features a new oxidant, an easy to handle procedure, high isolated yields, and good to excellent functional group tolerance even in the presence of vulnerable secondary alcohols and tert-butanesulfinamides.
