Methyl cavitand (I) (1.00 g, 1.15 mmol) and N-bromosuccinimide (0.90 g, 5.04 mmol) were added to CCl4 (100 ml). A catalytic amount of benzoyl peroxide was added to the solution, and the solution allowed to reflux overnight under irradiation of white light. The orange solution accompanied by a succinimide precipitate was then allowed to cool to room temperature. The precipitate was filtered off, and the orange filtrate concentrated on a rotary evaporator. The resulting solid was chromatographed on silica gel using a chloroform mobile phase. The fractions that were collected were concentrated on a rotary evaporator, and the orange solid product stirred in methanol overnight. The solution was then filtered, and the purified product dried overnight to yield the title compound as a dark orange powder.

Crystals suitable for X-ray crystallography were grown by slow liquid diffusion of methanol into a solution of the title compound in 1:1 e thyl acetate:hexane.
Hydrogen atoms, first located in the difference map, were positioned geometrically and allowed to ride on their respective parent atoms, with C—H bond lengths of 1.00 (CH), 0.99 (CH2), or 0.98 (CH3). They were then refined with a riding model with Uiso(H) = 1.5Ueq(CH3) and Uiso(H) = 1.2Ueq(X) for X = CH or CH2. Two of the four pentyl groups are disordered. These were refined over two positions using SIMU, SADI and DELU restraints with the final occupancies being 0.681 (5) for atoms C49—C51, C53—C56 and 0.319 (5) for atoms C49A—C51A, C53A—C56A. In addition, atoms C53—C56 and C53A—C56A were refined isotropically as they did not refine well when refined anisotropically. This is likely due to the presence of further structural disorder which is not fully accounted for by the current disorder model. The atom O1W was introduced into the structural model to account for an electron density feature of approximately 1.4 e/Å3. Its coordinates and sof were refined with its Uiso fixed. This feature is interpreted as the O atom of a water molecule but its low occupancy factor [0.415] has prevented discovery of the associated H atoms which are, therefore, absent from the structural model.
The title compound, (II, Scheme 1), has been previously prepared by Boerrigter et al. (1997), as the result of a free radical bromination of (I) using N-bromosuccinimide and the radical initiator, AIBN. The synthesis of (II) in this study, however, followed the synthetic conditions as set out by Sorrell & Pigge (1993), which used benzoyl peroxide as the radical initiator. Interestingly, this is despite observations by Boerrigter et al. that this protocol did not afford the desired product. Indeed, the conditions of Sorrell & Pigge, in conjunction with the use of white light, yielded 76% of pure (II).
In the title compound the [4]arene moiety is a cyclic tetramer. The labelling scheme for one of the monomers, shown in Fig.1, extends over the whole molecule.
The asymmetric unit of (II) is shown in Fig. 2. The bond lengths and bond angles all fall within the normal ranges and are not discussed further. The four bromine atoms which appear at the upper rim of the molecule are orientated such that all four face inwards towards the molecular cavity. Interestingly, (II) appears with a water molecule of partial (0.42) occupancy inside the molecular cavity. This is despite the hydrophobic nature of the cavity. Such partial occupancy has been reported in related structures; for examples see Tunstad et al., (1989) and Cram et al.,(1988).
The bromine atoms give rise to interesting packing arrangements in the crystal structure of (II). As shown in Fig. 3, the individual resorcin[4]arene cavitand molecules pack such that the bromine atoms are in close contact with the corresponding bromine atoms of a neighbouring molecule. This results in alternate layers of bromine atoms, in between the cavities and the 'feet' (pentyl groups) representing the remainder of the cavitand molecules.
In Fig. 4, the feet of (II) are such that two adjacent pentyl groups are linear, while the remaining two are bent. This is due to the interdigitation of a pair of linear chains from one cavitand molecule, with the corresponding chains of a neighbouring cavitand molecule. This results in insufficient space for the remaining pairs of alkyl groups to extend in a linear fashion.

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. |

The title compound, (II, Scheme 1), has been previously prepared by Boerrigter et al. (1997), as the result of a free radical bromination of (I) using N-bromosuccinimide and the radical initiator, AIBN. The synthesis of (II) in this study, however, followed the synthetic conditions as set out by Sorrell & Pigge (1993), which used benzoyl peroxide as the radical initiator. Interestingly, this is despite observations by Boerrigter et al. that this protocol did not afford the desired product. Indeed, the conditions of Sorrell & Pigge, in conjunction with the use of white light, yielded 76% of pure (II).
In the title compound the [4]arene moiety is a cyclic tetramer. The labelling scheme for one of the monomers, shown in Fig.1, extends over the whole molecule.
The asymmetric unit of (II) is shown in Fig. 2. The bond lengths and bond angles all fall within the normal ranges and are not discussed further. The four bromine atoms which appear at the upper rim of the molecule are orientated such that all four face inwards towards the molecular cavity. Interestingly, (II) appears with a water molecule of partial (0.42) occupancy inside the molecular cavity. This is despite the hydrophobic nature of the cavity. Such partial occupancy has been reported in related structures; for examples see Tunstad et al., (1989) and Cram et al.,(1988).
The bromine atoms give rise to interesting packing arrangements in the crystal structure of (II). As shown in Fig. 3, the individual resorcin[4]arene cavitand molecules pack such that the bromine atoms are in close contact with the corresponding bromine atoms of a neighbouring molecule. This results in alternate layers of bromine atoms, in between the cavities and the 'feet' (pentyl groups) representing the remainder of the cavitand molecules.
In Fig. 4, the feet of (II) are such that two adjacent pentyl groups are linear, while the remaining two are bent. This is due to the interdigitation of a pair of linear chains from one cavitand molecule, with the corresponding chains of a neighbouring cavitand molecule. This results in insufficient space for the remaining pairs of alkyl groups to extend in a linear fashion.
