WitrynaThe importance of these reactions is emphasized as the formation of acids and alcohols is often ascribed to direct CO 2 reduction products. ... Aldehydes with α-H atoms do not undergo the Cannizzaro disproportionation, as the aldol reaction is much faster. In the aldol reaction, C–C bond formation occurs by addition of the α-carbon of one ...
Witryna4 lip 2024 · Decarboxylative aldol reaction of aliphatic carboxylic acids is a useful method for C–C bond formation because carboxylic acids are an easily available class of compounds. In this study, we found that the decarboxylative aldol reaction of tertiary β-ketocarboxylic acids and trifluoropyruvates proceeded smoothly to yield the … WitrynaThe mechanism of aldol reactions in pure water has been studied with density functional calculations (B3LYP/6-311++G (3d,3p)//B3LYP/6-31G (d)). The reaction is a three-step process that involves: (1) water autoionization generates catalytic hydroxide and hydronium ions, (2) hydroxide and hydronium ions rapidly convert donor …
