Acetic acid aldol reactions in the presence of trimethylsilyl trifluoromethanesulfonate.
In the presence of TMSOTf and a trialkylamine base, acetic acid undergoes aldol addition to non-enolizable aldehydes under exceptionally mild conditions. Acidic workup yields the beta-hydroxy carboxylic acid. The reaction appears to proceed via a three-step, one-pot process, including in situ trimethylsilyl ester formation, bis-silyl ketene acetal formation, and TMSOTf-catalyzed Mukaiyama aldol...
متن کاملKinetics of Decomposition Reactions of Acetic Acid Using DFT Approach
Excessive amount of oxygen content in unprocessed bio-oil deteriorates the quality of bio-oil which cannot be used in transportation vehicles without upgrading. Acetic acid (CH3COOH) is a vital component of ‘acids’ catalogue of unprocessed bio-oil produced from thermochemical conversions of most of biomass feedstocks such as switchgrass, alfalfa, etc. In this study, the decomposition reactions ...
متن کاملSyn-selective silicon Mukaiyama-type aldol reactions of (pentafluoro-λ6-sulfanyl)acetic acid esters with aldehydes
Aldol reactions belong to the most frequently used C-C bond forming transformations utilized particularly for the construction of complex structures. The selectivity of these reactions depends on the geometry of the intermediate enolates. Here, we have reacted octyl pentafluoro-λ6-sulfanylacetate with substituted benzaldehydes and acetaldehyde under the conditions of the silicon-mediated Mukaiy...
متن کاملAcetic Acid in Cholera
The treatment of cholera by acetic acid, suggested by Dr. Greene in the September number of the Indian Medical Gazette, deserves, I think, to be put to the test by the profession. When I perused Dr. Greene's article, it struck me that, from its strong antiseptic property, acetic acid may do good by counteracting the morbific influence of the cholera miasm in the blood. Besides, being a stimulan...
