(Received 15 November 2007; accepted 1 February 2008; online 13 February 2008)

The title compound, C16H26O2, was easily obtained in high yield when 4-bromo­methyl-2,6-di-tert-butyl­phenol was reacted with methanol. There are two independent mol­ecules in the asymmetric unit. The meth­oxy group in each of the independent mol­ecules was found to be disordered, with site-occupation factors of 0.8728 (18)/0.1272 (18) and 0.8781 (17)/0.1219 (17).

Comment top

Hindered phenol antioxidants are widely used in polymers and lubricants. It could protect polymers by increasing both their process stability and long-term stability against oxidative degradation (Yamazaki & Seguchi, 1997). In former papers, we have reported the reaction of 4-bromomethyl-20,6-di-tet-butyl-phenol with amines (Zeng et al., 2005) and it was showed that the 4-bromomethyl-2,6-di-tet-butyl-phenol was highly reactive. The title compound, C16H26O2,(1),has been easily synthesied when we tried to dissolve the 4-bromomethyl-2,6-di-tert-butyl-phenol in methanol. It was found that there are two independent molecules in the asymmetric units. The phenolic hydroxyl are hindered by the adjacent tert-butyl groups. And both of the methoxyl groups in the two molecules were found disordered with with site occupation fators 0.8728 (18)/0.1272 (18) and 0.8781 (17)/0.1219 (17).

Experimental top

The 4-bromomethyl-2,6-di-tert-butyl-phenol (7.15 g) was synthesized from 2,6-di-tert-butyl-4-methylphenol (5.5 g, 0.025 mol) and equivalent NBS (Rieker et al., 1968) in a yield of 96%. Then 40 ml me thanol was added and stirred for 5 min the produt (5.85 g, 0.023 mol) was obtained in a yield of 97.3%. Suitable crystals were obtained by slow evaporation of a mixture of ethyl acetate and ethanol.

Refinement top

The H atoms of O—H were initially located in a difference Fourier Map and restrained on their parent atoms with O—H restrained 0.82 Å. In absence of significant anomalous dispersion effects, Friedel-pair reflections were merged prior to refinement. All H other atoms were positioned geometrically and refined using a riding model, in the range of 0.93–0.97 Å, with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(Cmethyl).

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.
