2-[(4-Chlorophenyl)(hydroxy)methyl]-5,5-dimethyl-1,3,2-dioxaphosphinan-2-one

Abstract top

In the title compound, C12H16ClO4P, the phosphonate ring adopts a chair conformation. In the crystal, intermolecular O-H...O hydrogen bonds link the molecules into chains propagating along the b axis.

Comment top

Acyclic alpha-hydroxyphosphonates and cyclic alpha-hydroxyphosphonates can be used as very convenient intermediates. They are also an attractive class of biologically active compounds (Peng et al., 2007; Liu et al., 2006). In our research work aimed at searching for novel agrochemicals, we have attempted to synthesize hydroxyphosphonate derivatives using literature procedures. Here we report the crystal structure of the title compound (Fig. 1). The bond lengths (Allen et al., 1987) and angles show normal values. The crystal structure is stabilized by intermolecular O—H···O hydrogen bonds (Table 1, Fig. 2).

Related literature top

For the synthesis of hydroxyphosphonates, see: Zhou et al. (2008). For the synthesis and biological activity of hydroxyphosphonate derivatives, see: Peng et al. (2007); Liu et al. (2006). For standard bond lengths, see: Allen et al. (1987).

Experimental top

The title compound was prepared according to literature procedures (Zhou et al. 2008). 4-Chlorobenzaldehyde (10 mmol) was added to a solution of 5,5-dimethyl-1,3,2-dioxaphosphinane (10 mmol) in triethylamine (10 mmol). The mixture was stirred at room temperature for 20 h. Pure title compound was afforded by column chromatography on silica gel (acetone/petroleum ether 1:2). Recrystallization from ethyl acetate over a period of one week gave colourless crystals of the title compound.

Refinement top

C-bound H atoms and the O-bound H atom were geometrically positioned (C—H 0.93–0.97 Å, O—H = 0.82 Å) and refined as riding, with Uiso(H) =kUeq(C, O), where k = 1.5 for methyl H and OH and 1.2 for other H atoms.

Special details top

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.
