Khorshidi, Alireza published the artcileMagnetite nanoparticles catalyzed preparation of isatin ketals under solvent-free conditions promoted by ultrasound irradiation, Application In Synthesis of 177-10-6, the publication is Arabian Journal of Chemistry (2019), 12(8), 2470-2475, database is CAplus.
Fe3O4 magnetic nanoparticles (MNPs) were synthesized via chem. precipitation method and used as an efficient and recyclable catalyst in ketalization of isatins I (X = H, 5-Cl, 5-Br, 7-Cl). It was found that a solvent-free process, under irradiation of sonic waves provides good to excellent yields of the desired ketals II (n = 2, 3).
Arabian Journal of Chemistry published new progress about 177-10-6. 177-10-6 belongs to dioxole, auxiliary class Dioxolane,Spiro, name is 1,4-Dioxaspiro[4.5]decane, and the molecular formula is C8H14O2, Application In Synthesis of 177-10-6.
