I found the field of Chemistry very interesting. Saw the article On Water Catalytic Aldol Reaction between Isatins and Acetophenones: Interfacial Hydrogen Bonding and Enamine Mechanism published in 2019.0. Quality Control of 1-(4-Nitrophenyl)ethanone, Reprint Addresses Xu, LW; Jian, YJ (corresponding author), Shaanxi Normal Univ, Sch Chem & Chem Engn, MOE, Key Lab Appl Surface & Colloid Chem, Xian 710062, Shaanxi, Peoples R China.; Xu, LW (corresponding author), Hangzhou Normal Univ, Minist Educ, Key Lab Organosilicon Chem & Mat Technol, Hangzhou 310012, Zhejiang, Peoples R China.. The CAS is 100-19-6. Through research, I have a further understanding and discovery of 1-(4-Nitrophenyl)ethanone
On water catalytic aldol reaction catalyzed by polyetheramine (D230) has been developed for easy access to 3-substituted 3-hydroxyindolin-2-ones through the reaction between various substituted isatins and acetophenones/cyclic ketones in high yields under room temperature. Systematic mechanism investigation uncovers the secret for the on water catalytic aldol reaction: comparison of the heterogeneous and homogeneous reaction circumstances with yields of 95 and 20%, respectively, indicates the on-water reaction dominating; interfacial hydrogen bonding between isatin with H2O is tested based on the downfield shift of the C2 and C3’s C-13 NMR signals when water was added to the CDCl3 solution of isatin; Lewis base polyetheramine D230 catalyzes the aldol reaction via the enamine mechanism verified by in situ NMR and ESI-MS analysis.
