I found the field of Chemistry; Engineering very interesting. Saw the article Selective C3-alkenylation of oxindole with aldehydes using heterogeneous CeO2 catalyst published in 2020.0. Formula: C8H7NO, Reprint Addresses Siddiki, SMAH; Shimizu, K (corresponding author), Hokkaido Univ, Inst Catalysis, N-21,W-10, Sapporo, Hokkaido 0010021, Japan.; Shimizu, K (corresponding author), Kyoto Univ, Elements Strategy Initiat Catalysts & Batteries, Kyoto 6158520, Japan.. The CAS is 59-48-3. Through research, I have a further understanding and discovery of Indolin-2-one
We report herein that a commercially available CeO2 is an active and reusable catalyst for the C3-selective alkenylation of oxindole with aldehydes under solvent-free conditions. This. catalytic method is generally applicable to different aromatic and aliphatic aldehydes, giving 3-alkyledene-oxindoles in high yields (87%-99%) and high stereoselectivities (79%-93% to E-isomers). This is the first example of the catalytic synthesis of 3-alkenyl-oxindoles from oxindole and various aliphatic aldehydes. The Lewis acid-base interaction between Lewis acid sites on CeO2 and benzaldehyde was studied by in situ IR. The structure-activity relationship study using CeO2 catalysts with different sizes suggests that defect-free CeO2 surface is the active site for this reaction.
