Abstract
The asymmetric unit of the title salt, C28H28O3P+·Cl−·H2O, contains a benzyltriphenylphosphonium cation, a chloride counter-ion, and a water molecule of crystallization. The 3,4,5-trimethoxy substituents of the benzylic functionality are arranged with the 3,5-methyl groups lying approximately in the aromatic ring plane while the 4-methyl group is out of the plane.

Comment
The 3,4,5-trimethoxyphenyl group is found in a number of natural products with antifungal properties such as Brittonin A and B (Asakawa et al., 1976), and central nervous system therapeutic properties such as Kadsurin (Mervič et al., 1977). A number of anticancer chalcones also contain this functionality (Lawrence et al., 2006); common synthetic routes to these products involve Wittig chemistry or Knoevenagel condensation reactions. The title compound is a Wittig precursor requiring deprotonation in the presence of a carbonyl compound.
The activity of the molecule classes above is believed to be related to the conformation of the 3,4,5-trimethoxyphenyl group relative to the other aromatic ring present. One aspect of this may be due to the disposition of the three methoxy groups, and the title molecule was chosen to provide a simple starting reference point for a more extensive study.
The structure obtained shows that O—C vectors are directed at 7, 81, and 8° to the phenyl ring plane for the 3,4, and 5-methoxy groups respectively.
Experimental
The title compound was obtained from 3,4,5-trimethoxybenzyl alcohol in two steps.
The alcohol (20 g, 0.1 mol) was dissolved in diethylether (200 ml) and cooled to 0°C. Thionyl chloride (15 ml, 0.21 mol) was added dropwise over thirty minutes and the solution was stirred for two hours. Water (120 ml) was added portionwise and the ether layer was separated. Extraction of the aqueous layer with diethylether (3 x 25 ml), combination of the ether fractions, drying over granular calcium chloride, and removal of the solvent under reduced pressure gave white microcrystalline 3,4,5-trimethoxybenzyl chloride in near quantitative yield.
The product from the first stage was mixed with triphenylphosphine (37.2 g, 0.115 mol). Addition of toluene (200 ml) and pump-purging with nitrogen gave a colourless solution which was heated under nitrogen at reflux temperature for thirty hours. The reaction mixture was allowed to cool to room temperature before being filtered under nitrogen. The white microcrystalline product was washed with petroleum ether and dried under reduced pressure (42.1 g, 72%).
Crystallization of a small sample by layering petroleum ether (40–60°C) onto a concentrated dichloromethane solution produced crystals suitable for the structure determination.
Refinement
H atoms bonded to the O atom were located in a difference map and refined with distance restraints of O—H = 0.84 Å, and with Uiso(H) = 1.2Ueq(O). Other H atoms were positioned geometrically and refined using a riding model, with C—H = 0.93–0.96 Å and with Uiso(H) = 1.2 (1.5 for methyl groups) times Ueq(C).

Special details
| 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. |
