Deka, Nabajyoti published the artcileMicrowave mediated solvent-free acetylation of deactivated and hindered phenols, Category: tetrahydropyran, the publication is Green Chemistry (2001), 3(5), 263-264, database is CAplus.
Deactivated and sterically hindered phenols have been acetylated with acetic anhydride under microwave irradiation using iodine as catalyst in an eco-friendly process. The reaction was carried out under solvent-free conditions and the acetates were obtained in nearly quant. yields with dramatic reduction of reaction time compared to standard oil-bath heating.
Green Chemistry published new progress about 69097-99-0. 69097-99-0 belongs to tetrahydropyran, auxiliary class Other Aliphatic Heterocyclic,Benzene,Phenol,Ether,Inhibitor, name is 5,7-Dihydroxy-2-(3-hydroxy-4-methoxyphenyl)chroman-4-one, and the molecular formula is C16H14O6, Category: tetrahydropyran.
