The title compound was obtained during the coupling tosyloxytropone and 4-flouroaniline in a 1:1 ration in toluene. On evaporation of the solvent; crystals suitable for X-Ray crystallography was obtained.
H atoms were positioned geometrically and refined using a riding model, with C—H = 0.95 Å and with Uiso(H) = 1.2 times Ueq(C aromatic).
In the current paper the title compound, (I), is presented as an example of a product formed during the exchange reaction of tosyloxytropone and the corresponding 4-flouroaniline. The compound is the first of a series of halogenated derivatives of tropolone type molecules, see Fig. 1. Two closely related derivatives of N-alkyl (Roesky & Burgstein, 1999) and N-aryl (Hicks & Brookhart, 2001) have been reported. The addition of a halogen moiety to the compound can drastically affect the packing of the molecule in the solid state.
Two independent molecules are present in the asymmetric unit, with the only observable difference being the rotation of the phenyl moiety compared to the tropone molecule. This is clearly illustrated by the torsional twist of the C—N—C—C (see Table 1) and the interplanar dihedral angle formed by the phenyl and seven membered tropone ring systems of 46.04 (3) and 41.45 (4) °, respectively.
Weak intra- and intermolecular interactions is observed in the solid state, see Table 2. The weak intermolecular hydrogen bonds form dimeric systems in the solid state consisting of the two independent units. The flouro moieties do have a significant effect on the packing of the molecule in the solid state, with C—F···H interactions being observed.

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. |

In the current paper the title compound, (I), is presented as an example of a product formed during the exchange reaction of tosyloxytropone and the corresponding 4-flouroaniline. The compound is the first of a series of halogenated derivatives of tropolone type molecules, see Fig. 1. Two closely related derivatives of N-alkyl (Roesky & Burgstein, 1999) and N-aryl (Hicks & Brookhart, 2001) have been reported. The addition of a halogen moiety to the compound can drastically affect the packing of the molecule in the solid state.
Two independent molecules are present in the asymmetric unit, with the only observable difference being the rotation of the phenyl moiety compared to the tropone molecule. This is clearly illustrated by the torsional twist of the C—N—C—C (see Table 1) and the interplanar dihedral angle formed by the phenyl and seven membered tropone ring systems of 46.04 (3) and 41.45 (4) °, respectively.
Weak intra- and intermolecular interactions is observed in the solid state, see Table 2. The weak intermolecular hydrogen bonds form dimeric systems in the solid state consisting of the two independent units. The flouro moieties do have a significant effect on the packing of the molecule in the solid state, with C—F···H interactions being observed.
