Application of 16859-59-9, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 16859-59-9, Name is 3-Hydroxyisobenzofuran-1(3H)-one, molecular formula is C8H6O3. In a Article，once mentioned of 16859-59-9
In the presence of sulfuric acid, 3-hydroxyphtalides a, b, and c react with anisol or m-dimethoxybenzene.Aromatic electrophilic substitution takes place and the corresponding 3-arylphtalides 1-5 are obtained.When the other substituant in position 3 is H, the reaction can continue with phtalide ring opening, in the presence of either sulfuric acid or aluminium chloride, and a second intermolecular alkylation gives the triarylmethanes 6-9. 3,4,5,6-Tetrahydrophtalic anhydride reacts with benzene to give lactol 10 which, with anisol, leads to lactone 11.This lactone isomerizes with intramolecular alkylation to the tetrahydro-1H-fluorenecarboxylic acid 12.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Application of 16859-59-9. In my other articles, you can also check out more blogs about 16859-59-9
