Reference of 89424-83-9, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 89424-83-9, Name is 1,3-Dihydroisobenzofuran-5-carbaldehyde, molecular formula is C9H8O2. In a Article，once mentioned of 89424-83-9
The Horner-Wadsworth-Emmons (HWE) reaction of the diethyl ester of 2-amino-2-oxoethylphosphonic acid 1 as well as of diethyl ester of the 2-dimethylamino-2-oxoethylphosphonic acid 2 with some aldehydes and ketones 3 in liquid-solid two phase system is used for the preparation of alpha,beta-unsaturated amides 4, 5. The synthesis is carried out in mild conditions (room temperature, KOH, K2CO3, CaO) in the absence of a catalyst or in the absence of a solvent, and leads in very high (E)-stereoselectivity and in high yields to en-amides.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Reference of 89424-83-9. In my other articles, you can also check out more blogs about 89424-83-9
