This reaction has come to be known as the Aldol reaction, or “aldol addition reaction” to distinguish them from cases where water is lost to give a new C-C double bond (that’s the aldol condensation, see part 3) This type of reaction can also work for ketones (see below) and othe...

The addition of an enolate to an aldehyde molecule is called the "aldol addition reaction." A subsequent step of heating the aldol in the presence of a base compound produces the "aldol condensation product."What is an Aldol? An aldol is a class of organic compounds containing a 3-hydroxy...

(1pand2j). Also the activity of this mutant towards 3-substituted endocyclic enones (1q,rand2k,l), which again poorly accepted by wt-YqjM was significantly improved. Hence, we are convinced that YqjM (I69Y/C26G), beyond the scope of this contribution is a valuable addition to the ...

摘要: Rapid addition of a tertiary amine to tin(IV) chloride–selenoacetal mixtures leads to the corresponding vinyl selenides in good yield, whereas slow addition of the amine base gives aldol condensation products.关键词: fluorescence counterstain nuclear counterstain immunocytochemistry propidium iodide...

The oxygen vacancies and SBET were used to assess the activity of the perovskite catalysts in the cross-aldol condensation reaction. The optimal conditions for this aldol condensation were found to be 120 °C after 25 h with no solvent using SrMo0.5Ni0.5O3-δ inorganic perovskite which had ...
