Abstract

The title enamino ketone, C12H15NO, a derivative of 4-(phenyl­amino)­pent-3-en-2-one, presents a roughly planar [greatest displacement of an atom from the pentenone plane is 0.033 (2) Å] pentenone backbone, enhanced by an intra­molecular N—H⋯O hydrogen bond; the asymmetry in C—C distances in the group suggests the presence of unsaturated bonds. The overall geometry in the free ligand differs significantly from that in other reported compounds, in which it is coordinated to rhodium; this is reflected in the bond distances [the N⋯O distance is significantly increased (0.2 Å) upon coordination to the metal] and the dihedral angle between the benzene ring and the pentenone backbone [49.53 (5)°]. All of the methyl goups are rotationally disordered over two orientations of equal occupancy.

Comment

A well-known system in organometallic chemistry is the β-diketone compound AcacH (acetylacetone; or when coordinated acetylacetonato, acac-). A multitude of derivatives have been synthesized to date, with enaminoketones being one type. Since enaminoketones contain nitrogen and oxygen atoms as well as an unsaturated C—C bond, these electron-rich compounds are of interest in various fields including liquid crystals [Pyżuk et al. (1993)], fluorescence studies [Xia et al. (2008)] as well as formation of complexes of medical interest [Tan et al. (2008); Chen & Rhodes (1996)]. It also has significant application possibilities in catalysis [Nair et al. (2002); Van Aswegen et al. (1991); Steyn et al. (1992; 1997); Otto et al. (1998); Roodt & Steyn (2000); Brink et al. (2010)].

The title enaminoketone is a derivative of 4-(phenylamino)pent-3-en-2-one [PhonyH; Shaheen et al. (2006)]. Fig. 1 shows a view of the molecule. The C2–C3 distance of 1.383 (3) Å, versus the C3–C4 distance of 1.420 (2)Å indicates an unsaturated bond in the pentenone backbone, which is otherwise planar, probably helped by an intramolecular N1—H1···O1 bond (N1—H1: 0.91Å; H1···O1: 1.90Å; N1···O1:2.635 (2)Å, N1—H1···O: 136.4°). In general terms, the geometry in the free ligand differs significantly from that in other reported compounds where it is coordinated to rhodium [Table1; Venter et al. (2009a; 2009b); Damoense et al. (1994)]; fon instance, the N1···O1 distance is greatly ncreased (~0.2 Å) upon coordination to the metal, as it is the dihedral angle between the phenyl ring and the pentenone backbone. All the methyl goups appear rotationally disordered in two sites of similar occupation.

Experimental

A solution of acetylacetone (11.07 g, 0.1106 mol), 2-Me-aniline (10.73 g, 0.1008 mol) and 2 drops of H2SO4(conc.) in 150 ml benzene was refluxed for 6 hours in a DeanStark trap, filtered and left to crystallize. Crystals suitable for X-Ray diffraction were obtained in 17.86 g (94.32 %) yield. This compound is stable in air and light over a period of several months.

Refinement

The methyl and aromatic H atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms, with C—H = 0.95 and 0.98Å and Uiso(H) = 1.5Ueq(C) and 1.2Ueq(C), respectively. The methyl groups were generated to fit the difference electron density and the groups were then refined as rigid rotors. The highest residual electron-density peak is 0.47Å from H1F.

Special details

Experimental. The intensity data was collected on a Bruker X8 ApexII 4 K Kappa CCD diffractometer using an exposure time of 60 seconds/frame. A total of 688 frames were collected with a frame width of 0.5° covering up to θ = 28.24° with 99.1% completeness accomplished.
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.
