The title compound was prepared by taking equimolar quantities of 4-(prop-2-ynyloxy)benzenamine (14.7 g, 0.1 mol) and maleic anhydride (9.8 g, 0.1 mol) in 80 ml benzene and 20 ml DMF and refluxing 4 h in the presence of p-toluenesulfonic acid. The reaction product was poured into 500 ml ice water, yellow precipitate product was formed. The crude product was recrystalled from ethanol. Yield 90%. 1H NMR (300 MHz, DMSO-d6) δ 7.30, 7.13(d, aromatic), 7.02(s, 2H, maleimide), 4.85(s, 2H, –H2–), 3.14(s, 1H, ≡-H). Analysis. calculated for C13H9NO3: C 68.72, H 3.99, N 6.16%. Found: C 68.39, H 4.02, N 6.21%. The product added in 50 ml ethanol and crystals of (I) suitable for X-ray analysis were obtained by slow evaporation at room temperature.
The H atoms bound to C atoms were placed in caculated positions with C—H = 0.93 Å and included in the
with Uiso(H) = 1.2Ueq(C).Data collection: SMART (Bruker, 2000); cell

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

N-substituted maleimides can be used in free radical initiated polymerization process upon exposure to light (Chang, et al., 1999; Hoyle, et al.,1999). N-(3-Nitrophenyl)maleimide (Moreno-Fuquen, et al., 2006), N-(3-Chlorophenyl)maleimide (Moreno-Fuquen, et al., 2008a) and N-(4-Chlorophenyl)maleimide (Moreno-Fuquen, et al., 2008b) has reported and could be taken as a reference to compare with the structural characteristics of (I).
Perspective view of (I), showing the atomic numbering scheme, can be seen in Fig. 1. The dihedral angle between the benzene and imidic rings influences on the polymerization process, and subsituents of the benzene ring can effect the value of dihedral angle (Miller et al. 2000). In the title compound (I), the dihedral angle between the benzene and maleimide is 64.1 (2)°. This angle is 46.46 (5) ° for N-(3-Chlorophenyl)maleimide (Moreno-Fuquen, et al., 2008:1) and 47.54 (9) ° for N-(4-Chlorophenyl)maleimide (Moreno-Fuquen, et al., 2008:2). The crystal structure of (I) is stabilized by weak intermolecular C—H···O hydrogen bonds.
