Description
N-Benzylphthalimide (NBPT), also known as 2-benzylisoindoline-1,3-dione, is an N-substituted phthalimide. It has been prepared by reacting phthalic anhydride with benzyl amine in glacial acetic acid. Vibrational spectra of NBPT has been recorded and assigned. NBPT is a roof-shaped molecule with a planar cyclic imide and a phenyl ring connected by a methylene group. Crystal structure of N-benzylphthalimide has parallel layers of phthalimides stack along the a axis.
Application
N-Benzylphthalimide may be used in the following syntheses:
2-benzyl-1,1,3,3-tetraphenylisoindoline
tailor-made highly fluorous porphyrin derivatives
N-benzylisoindole
