4,6-Di-tert-butyl-2,3-dihydroxybenzaldehyde

M. Arsenyev, E. Baranov, S. Chesnokov and G. Abakumov

Abstract top

The title compound, C15H22O3, crystallizes with two independent molecules in the asymmetric unit. In each molecule, one hydroxy group (at position 2) is involved in an intramolecular O-H...O hydrogen bond, and another one (at position 3) exhibits bifurcated hydrogen-bonding being involved in intra- and intermolecular O-H...O interactions. In the crystal, O-H...O hydrogen bonds link alternating independent molecules into chains running along [010].

Comment top

2,3-Dihydroxybenzaldehyde is well known building-block for preparing Schiff-base ligands containining catechol fragment. These ligands are used for the synthesis of polynuclear metal complexes (Belmonte et al., 2012), supramolecular compounds (Albrecht et al., 2004) and catalysts (Furutachi et al., 2010). Here we report the crystal structure of the title compound (I).

The asymmetric unit of (I) contains two independent molecules (Fig. 1) with non-typical arrangement of tert-butyl groups (orto- and para- despite meta-position relative to CHO-group). All bond lengths and angles in (I) are normal and correspond to those observed in the related 2,3-dihydroxybenzaldehyde (Ng, 2005). The structure shows two types of O—H···O hydrogen bonds (Table 1) - intra- and intermolecular ones.

In the crystal, intermolecular O—H···O hydrogen bonds link alternating independent molecules into chains running in [010] (Fig. 1).

Mixture of 3,5-di-tert-butyl-catechol (22.2 g, 0.1 mol), benzyl chloride (23.0 ml, 0.2 mol) and K2CO3 (27.6 g, 0.2 mol) in DMF (100 ml) was heated at 90°C for 24 h under argon atmosphere. After cooling, water (300 ml) was added to reaction mixture and the product was extracted by hexane (3*200 ml). Extract was dried by Na2SO4. The solvent was evaporated and the product was dried under vacuum. The yield was 39.4 g (98%). m.p.=86-87°C dH (200 MHz CDCl3) 7.48-7.28 (m, 10H, 2Ph), 7.02 (d, 1H, Car-H, JHH=2.2 Hz), 6.95 (d, 1H, Car-H, JHH=2.2 Hz), 5.16 (s, 2H, CH2Ph), 5.11 (s, 2H, CH2Ph), 1.43 and 1.32 (s, both 9H, t-Bu). dC (50 MHz CDCl3) 151.85, 145.71, 145.46, 142.73, 138.57, 137.33, 128.45, 128.22, 127.83, 127.79, 127.58, 127.33, 116.55, 110.78, 73.50, 71.44, 35.48, 34.80, 31.56, 30.87.

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.
