S1. Comment

Operational cross-linked polymers have been used for synthesis of multifunctional monomers (Starvin et al. (2004). These polymers are useful in many applications such as polymeric sorbents and preparing the laser composites (Kazuya et al., 2000); Ryusuke & Kazufumi (2001). In practice, for obtaining polymers of improved functional properties, polymerical transformations are carried out. However, preparation of such cross-linked copolymers have some difficulties related to monomers high reactivity (for example, divinybenzene) and other physico-chemical properties. Therefore, synthesis of multifunctional monomers based on the alkenylphenols is rather important. The authors were synthesised the multifunctional monomers (Bayramov et al., 2011), that can be used in preparation of cross-linked copolymers as a sorbent for heavy metals.

The molecule of title compound, C₂₈H₃₈O₂, (I), reveals a crystallographic inversion centre at the mid-point of the central C—C bond (Fig. 1). An asymmetric unit comprises a half of the molecule. The crystal packing displays intramolecular C—H···O hydrogen bonds and C—H···π interaction (Fig. 2, Table 1). The molecule has long chain of (CH₂) groups, and so, the polymers based on this monomer are capable to adsorbed heavy metal ions.

S2. Experimental

2-Propenylphenol (0.015 mol, 2 g) and KOH (0.015 mol, 0.84 g) were dissolved in 6 mL of 2-propanol, then 1,10-dibromedecane (0.006 mol, 1.8 g) was added to this solution. This mixture was stirred at 353 K for 30 m. The desired compounds with yield 2.43 g (99.1%) was filtered and washed with acetone and recrystallised to obtain colourless crystals. T_mp = 326 K. The structure of the reported compound - 1,10-bis{2(1-propenyl)phenoxy}decane, was also proved by NMR-spectroscopy. FT-NMR (acetone-d⁶, p.p.m.), ¹H: 1.92 d (6H,CH₃); 2.05 t (4H, CH₂); 4.16 t (4H, OCH₂); 6.13 m (2H, CH=); 6.67–7.2 m (8H, 2Ar); 7.3 d (2H,CH=). ¹³C: 18.5; 26.1; 67.1; 112.3; 121.4; 124.4; 126.0; 127.1; 127.3; 127.5; 156.0.

S3. Refinement

The hydrogen atoms were placed at calculated positions and refined in the riding mode with fixed isotropic displacement parameters [U_iso(H) = 1.2Ueq(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.
