N-Methylphthalimide Usage And Synthesis
Chemical PropertiesWhite powder
UsesPhotoreduction of N-methylphthalimide (NMP) with 2,3-dimethyl-2-butene h and the selective electroreduction of N-methylphthalimide to 3-hydroxy-2-methyl-isoindolin-1-one have been studied.
Synthesis Reference(s)The Journal of Organic Chemistry, 44, p. 497, 1979 DOI: 10.1021/jo01318a005
General DescriptionPhotoreduction of N-methylphthalimide (NMP) with 2,3-dimethyl-2-butene has been studied. The selective electroreduction of N-methylphthalimide to 3-hydroxy-2-methyl-isoindolin-1-one in ionic liquids and phenol as a proton donor under silent and ultrasonic conditions has been reported. Single electron transfer (SET)-induced photochemical reaction of NMP with silyl enol ether has been investigated. Nitration of NMP is reported to afford “exclusively” 3-nitro-derivative.
Purification MethodsRecrystallise the imide from absolute EtOH or AcOH (m 134o). The IR has max at 1780 and 1380cm -1. [Beilstein 21 H 461, 21 III/IV 5030.]
