Potassium phthalimide Chemical Properties,Usage,Production
Chemical Properties
slight yellow-green to white powder
Uses
Potassium Phthalimide is a green, solid-base organocatalys.
Uses
Condensation of phthalimide potassium with organic halide in dimethylformamide has been reported. Reaction of potassium phthalimide and sulfur monochloride in petroleum ether has been studied.
Uses
Potassium phthalimide is usually used as organocatalyst for the cyanosilylation of various carbonyl compounds under extremely mild conditions,and also used as reagent for the transformation of allyl- and alkyl halides into protected primary amines.
Synthesis
136918-14-4
1074-82-4
General procedure for the synthesis of phthalimide potassium salt from 3-hydroxy-1H-isoindol-1-one: Add phthalimide to the reactor with 3 times the mass of anhydrous ethanol, and heat it up to 60℃. A pre-prepared anhydrous ethanol solution of 30% potassium methanolate (molar ratio of potassium methanolate to phthalimide 1.2:1) was slowly added by dropping through a burette with a controlled dropping time of 3 hours, during which the temperature was slightly elevated (up to a maximum of 65 °C). After the reaction lasted for 10 hours, the reaction mixture was filtered, washed once with anhydrous ethanol, and dried to give a high-purity potassium salt of phthalimide with a purity of 99.3% and a molar yield of 98%.
Purification Methods
The solid may contain phthalimide and K2CO3 from hydrolysis. If too much hydrolysis has occurred (this can be checked by extraction with cold Me2CO in which the salt is insoluble, evaporate the Me2CO and weigh the residue), it would be better to prepare it afresh. If little hydrolysis has occurred, then recrystallise it from a large volume of EtOH, and wash the solid with a little Me2CO and dry it in a continuous vacuum to constant weight.
