4′-Chloro­biphenyl-3-yl 2,2,2-trichloro­ethyl sulfate

Abstract

The title compound, C14H10Cl4O4S, is a 2,2,2-trichloro­ethyl-protected precursor of 4′-chloro­biphenyl-3-yl sulfate, a sulfuric acid ester of 4′-chloro­biphenyl-3-ol. The Caromatic—O and O—S bond lengths of the Caromatic—O—S unit are comparable to those in structurally analogous biphenyl-4-yl 2,2,2-trichloro­ethyl sulfates with no electro­negative chlorine substituent in the benzene ring with the sulfate ester group. The dihedral angle between the aromatic rings is 27.47 (6)°.

Comment

Hydroxylated metabolites of polychlorinated biphenyls (OHPCBs) are present in the serum of humans (Bergman et al., 1994; Dirtu et al., 2010) and other animals (Buckman et al., 2006; Nomiyama et al., 2010). Recent studies also indicate that the mammalian cytosolic sulfotransferases catalyze the formation of sulfuric acid esters from OHPCBs (Liu et al., 2006; Liu et al., 2009; Wang et al., 2006). However, our knowledge of the metabolic and toxicologic significance of these sulfation reactions has been hindered by a lack of information on the structural and chemical properties of the sulfuric acid ester products. As one component of our continuing studies on the properties of the sulfuric acid esters of OHPCBs, we report here the structure of 4'-chloro-biphenyl-3-yl 2,2,2-trichloroethyl sulfate.

Several authors have proposed that the Caromatic—O and the corresponding O—S bond lengths are correlated with the stability of sulfuric acid conjugates (Brandao et al., 2005; Li et al., 2010a-c; Li et al., 2008). The Caromatic—O (i.e., C3'-O1) and O—S (i.e., O1—S1) bond lengths of the title compound are 1.4338 (17) Å and 1.5685 (11) Å, respectively. These values are comparable to the corresponding bond lengths reported for analogous biphenyl-4-yl 2,2,2-trichloroethyl sulfates with no electronegative chlorine substituent in the sulfated benzene ring (Li et al., 2010a-c; Li et al., 2008), which suggest that, analogous to biphenyl-4-yl sulfates, the 4'-chloro-biphenyl-3-yl sulfate corresponding to the title compound may be stable under physiological conditions (Brandao et al., 2005; Li et al., 2010c).

The dihedral angle of the biphenyl moiety of OHPCBs and, consequently, their sulfuric acid conjugates is associated with their affinity for cellular target molecules and, therefore, may correlate with their toxicity. The title compound adopts a solid state dihedral angle of 27.47 (6)°. The solid state dihedral angles of structurally related biphenyl-4-yl 2,2,2-trichloroethyl sulfates without ortho chlorine substituents ranges from 4.9 (2)° to 41.84 (16)° (Li et al., 2010a,b; Li et al., 2008). This large range of dihedral angles suggests, similar to the parent PCBs (Lehmler et al., 2002; Shaikh et al., 2008; Vyas et al., 2006), a conformational flexibility of the biphenyl moiety that allows the title compound and analogous biphenyl-4-yl sulfates to adopt an energetically less favorable conformation in the solid state due to crystal packing effects.

Experimental

The title compound was synthesized from 3',4'-dichlorobiphenyl-4-ol by sulfation with 2,2,2-trichloroethyl sulfonyl chloride using 4-dimethylaminopyridine as catalyst (Li et al., 2010c). Crystals suitable for crystal structure analysis were obtained by slowly evaporating a methanolic solution of the title compound.

Refinement

H atoms were placed in idealized positions and were constrained with distances of 0.99 Å for CH2 and 0.95 Å for CarH, and with Uiso(H) = 1.2Ueq of their attached C atom.

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 > 2σ(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.
