Abstract top

In the title compound, C16H17ClN2O4S, the dihedral angle between the phenyl and benzene rings is 19.4 (2)°. The crystal packing is stabilized by intermolecular N-H...O hydrogen bonds, as well as by intra- and intermolecular C-H...O hydrogen bonds.

Comment top

Since the vicinal haloamines are important building blocks in organic and medicinal chemistry, many attentions are attracted to the aminohalogenation reactions of functionalized alkenes (Kemp, 1991; Qui & Silverman, 2000). In recent years, many new aminohalogenation processes of several kinds of functionalized alkenes have been developed (Han et al., 2007), with the different nitrogen/halogen sources in the presence of metallic catalysts (Li et al., 2007). However, the aminohalogenation reactions of 2-nitro-propenyl benzene was not been well documented. Recently, we synthesized the title compound (I) from 2-nitro-propenyl benzene. As part of this study, we have undertaken the X-ray crystallographic analysis of (I) in order to elucidate the conformation and configuration of this product.

The bond lengths and angles in (I) are in good agree with expected values (Allen et al., 1987). The dihedral angle between the phenyl and benzene rings is 19.4 (2)°. The packing is stabilized by intermolecular N—H···O as well as intra and intermolecular C—H···O interactions in the crystal structure (Table 1).

Experimental top

N-cChlorosuccinimide (400 mg, 3.0 mmol) was added into a solution of MnSO4 (30.2 mg, 0.20 mmol), 1-benzyl-2-nitro-propene (163 mg, 1 mmol), tolunesulfonamide (513 mg, 3 mmol) and 4 Å molecular sieves (500 mg) in CH2Cl2 (5.0 ml) with nitrogen atmosphere. The resulting mixture was stirred at room temperature for 48 h. Reaction was quenched with saturated aqueous Na2S2O3 solution. The solid precipitates were filtered off and washed with ethyl acetate (3 × 10 ml). The organic solution was concentrated and then purified via flash chromatography (ethyl acetate/ hexane, 1:4, v/v) provide the title compound (I) as white solid (276 mg) in yield of 75%. A colourless crystal of (I) for X-ray analysis was obtained by slow evaporation from ethyl acetate solution system.

Refinement top

The H atom bonded to N was located in a difference map and refined with restraint of N—H = 0.89 (3) Å, and with Uiso(H) = 1.2Ueq(N). Other H atoms were geometrically placed and were treated as riding, with C—H distances of 0.93, 0.96 and 0.98 Å for aromatic, methyl and methine H atoms, respectively, and with Uiso(H) = 1.2Ueq(aromatic and methyne C) or 1.5Ueq(methyl C).

Special details top

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.
