2,3-Naphthalenedicarboxylic anhydride

N-(1'-Phenyl-2'-hydroxyethyl)-2,3-naphthylenedicarboximide(1a) was obtained by the reaction of 2,3-naphthylenedicarbonitrile with R-phenylglycinol. 2,3-Naphthylenedicarboxylic acid, when reacts with thionyl chloride, gives 2,3-naphthalenedicarboxylic acid cyclic anhydride rather than the corresponding 2,3-naphthalenedicarboxylic acid dichloride. The former, when reacts with S-leucinol, gives corresponding dicarboximide(1b). The crystal structure of compound 1a was determined by an X-ray single crystal diffraction analysis. Compound 1a: C₄₀H₃₀N₂O₆, F_W=634.66, orthorhombic, space group P2(1)2(1)2(1), a=1.15556(5) nm, b=3.16552(12) nm, c=0.85984(3) nm; α= 90°, β=90°, γ=90°, V=3.1452(11) nm³, Z=4, F(000)=1328, D_c=1.340 g/cm³, μ=0.091 mm^-1. Reflections collected/unique, 28053/4068(R_int=0.0411); Final R indices [I>2σ(I)]: R₁=0.0337, wR₂=0.0687; Largest diff. peak and hole, 248 and -222 e·nm^-3.
