Inaba, Masanori published the artcileNucleophilic fluoroalkylation/cyclization route to fluorinated phthalides, Name: Trimethyl(perfluorophenyl)silane, the publication is Beilstein Journal of Organic Chemistry (2018), 182-186, database is CAplus and MEDLINE.
A versatile and practical method for the synthesis of C3-perfluoroalkyl-substituted phthalides in a one-pot manner was described. Upon treatment of KF or triethylamine, 2-cyanobenzaldehyde reacted with (perfluoroalkyl)trimethylsilanes via nucleophilic addition and subsequent intramol. cyclization to give perfluoroalkylphthalides in good yields.
Beilstein Journal of Organic Chemistry published new progress about 1206-46-8. 1206-46-8 belongs to catalysis-chemistry, auxiliary class Organic Silicones, name is Trimethyl(perfluorophenyl)silane, and the molecular formula is C9H9F5Si, Name: Trimethyl(perfluorophenyl)silane.
