Ball-Milling Assisted Iron-Catalyzed Difluoromethylation Toward the Synthesis of Valuable Oxindoles. [PDF]

open access: yesChemSusChem
An iron‐catalyzed difluoroalkylation of acrylamides under ball‐milling conditions affords oxindoles in up to 85% yield. Analytical studies reveal that the apparent piezoelectric activity originates from iron leaching caused by milling assembly abrasion during the reaction process. The iron‐catalyzed process proves to be efficient with a broad substrate

Non-Palladium-Catalyzed Approach to the Synthesis of (E)-3-(1,3-Diarylallylidene)Oxindoles

open access: yesMolecules, 2022
Two novel synthetic approaches for synthesizing (E)-3-(1,3-diarylallylidene)oxindoles from oxindole were developed. All previously reported methods for synthesizing 3-(1,3-diarylallylidene)oxindoles utilized palladium-catalyzed reactions as a key step to
