Chemische Eigenschaften
N-Hydroxyphthalimide is yellow moist powder
Verwenden
Catalyst for oxidation reactions.
Verwenden
Aerobic oxidation of various alcohols has been accomplished by using a new catalytic system, N-hydroxyphthalimide (NHPI) combined with Co (acac). A practical catalytic method to convert alkylbenzenes into the corresponding carboxylic acids under atmospheric dioxygen at ambient temperature using a combined catalytic system consisting of N-hydroxyphthalimide (NHPI) and Co (OAc) 2 was developed. Novel catalysis by N-hydroxyphthalimide in the oxidation of organic substrates by molecular oxygen was described. Free radical functionalization of organic compounds catalyzed by N-hydroxyphthalimide. Purely organic and catalytic systems of anthraquinones and N-hydroxyphthalimide efficiently promote oxygenation of hydrocarbons with dioxygen under mild conditions. Hydroxylation of polycyclic alkanes with molecular oxygen catalyzed by N-hydroxyphthalimide (NHPI) combined with was transition metal salts.
Verwenden
N-Hydroxyphthalimide，additives in to DCC method of peptide synthesis used to improve yield of optically pure product.
Application
N-Hydroxyphthalimide is used in the synthesis of a new class of antibacterials potent against macrolide resistant bacteria. Also used in the synthesis of pyrazolidines, isoxazolidines and tetrahydrooxazines.

läuterung methode
N -Hydroxyphthalimide [524-38-9] M 163.1, m 230o, ~235o(dec), 237-240o, 7.0. Dissolve the imide in H2O by adding Et3N to form the salt and while hot, acidify, cool and pour into a large volume of H2O. Filter off the solid, wash it with H2O and dry it over P2O5 in a vacuum.
