1. Comment
==========

Functionalized benzimidazoles represent an important class of N-containing heterocyclic compounds and have received considerable attention in recent times because of their applications as antiulcers, antihypertensives, antivirals, antifungals, anticancers and antihistamines among others (Gravatt *et al.*, 1994; Soderlind *et al.*, 1999). They are also important intermediates in many organic reactions (Bai *et al.*, 2001) and act as ligands to transition metals for modelling biological systems (Bouwman *et al.*, 1990). In addition, the treatment potency of benzimidazoles in diseases such as ischemia--reperfusion injury (Zhu *et al.*, 2008), hypertension (Ogino *et al.*, 2008), obesity (Shah *et al.*, 2008) *etc*. have been recently reported.

In continuation of our research work devoted to the development of substituted benzimidazol-2-one derivatives (Belaziz *et al.*, 2012, 2013), we reported a synthesis of new benzimidazol-2-one derivative differently substituted by action of allylbromide with 1-benzyl -1*H*-benzo\[*d*\]imidazol-2(3*H*)-one in the presence of a catalytic quantity of tetra-n-butylammonium bromide under mild conditions to obtain disubstituted compound (Scheme 1).

The molecule of title compound, 1-allyl-3-(benzyl)-1*H*-benzo\[*d*\]imidazol-2(3*H*)- one, is built up from two fused five- and six-membered rings linked to a benzyl substituent and an allyl group as shown in Fig. 1. The fused rings system (N1, N2, C1-C7) is essentially planar with the largest deviation from the mean plane being -0.006 (2) A° at C5 atom. The benzyl group and the allyl group are almost perpendicular to the benzo\[*d*\]imidazol-2(3*H*)-one as indicated by the dihedral angles of 80.6 (1) and 77.4 (3) °, respectively.

In the crystal, the molecules are linked by C3--H3···O1 and C14--H14···O1 hydrogen bonds in the way to build two-dimensional network as shown in Fig. 2 and Table 2.

2. Experimental {#experimental}
===============

To 1*H*-benzo\[*d*\]imidazol-2(3*H*)-one (0.2 g, 1.49 mmol), potassium carbonate (0.41 g, 2.98 mmol) and tetra-n-butylammonium bromide (0.05 g, 0.15 mmol) in DMF (20 ml) was added benzylchloride (0.22 g, 1.79 mmol). Stirring was continued at room temperature for 6 h. The resulting salt was removed by filtration and the filtrate concentrated under reduced pressure. The residue was separated by chromatography on a column of silica gel with ethyl acetate/hexane (1/2) as eluent. The compound was recrystallized from ethanol to give colorless crystals. To the compound obtained (1-benzyl-benzimidazol-2-one (0.15 g, 0.67 mmol) was added allylbromide (0.10 g, 0.87 mmol) in DMF (10 ml), and potassium carbonate (0.18 g, 1.33 mmol) and tetra-n-butylammonium bromide (0.02 g, 0.07 mmol). Stirring was continued at room temperature for 12 h. The formed salt was removed by filtration and the filtrate concentrated under reduced pressure. The residue was separated by chromatography on a column of silica gel with ethyl acetate/hexane (1/1) as eluent (yield 82%, based on the intermediate). The title compound was recrystallized from dichloromethane/hexane to give colourless crystals.

3. Refinement {#refinement}
=============

All H atoms could be located in a difference Fourier map. However, they were placed in calculated positions with C---H = 0.93 Å (aromatic, olefinic), and C---H = 0.97 Å (methylene) and refined as riding on their parent atoms with *U*~iso~(H) = 1.2 *U*~eq~ (C).

  Geometry. All s.u.\'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.\'s are taken into account individually in the estimation of s.u.\'s in distances, angles and torsion angles; correlations between s.u.\'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.\'s is used for estimating s.u.\'s involving l.s. planes.
  Refinement. Refinement of *F*^2^ against all reflections. The weighted *R*-factor *wR* and goodness of fit *S* are based on *F*^2^, conventional *R*-factors *R* are based on *F*, with *F* set to zero for negative *F*^2^. The threshold expression of *F*^2^ \> σ(*F*^2^) is used only for calculating *R*-factors(gt) *etc*. and is not relevant to the choice of reflections for refinement. *R*-factors based on *F*^2^ are statistically about twice as large as those based on *F*, and *R*- factors based on all data will be even larger.
