(Received 21 November 2007; accepted 24 December 2007; online 9 January 2008)

The title compound, C22H31NO, has been synthesized from 4-bromo­methyl-2,6-di-tert-butyl­phenol and N-methyl­aniline. There are two independent mol­ecules in the asymmetric unit. The aniline ring in each of the independent mol­ecules was found to be disordered, with site occupation factors 0.621 (10)/0.379 (10) and 0.605 (10)/0.395 (10).

Comment top

Hindered phenol antioxidants are widely used in polymers and lubricants. They protect polymers by increasing both their process stability and long-term stability against oxidative degradation (Yamazaki and Seguchi, 1997).

There are two independent molecules in the crystal structure. Both of the two aniline rings in the two independent molecules were found disordered.

The bond lengths and angles of the crystal are within normal ranges and selected values are given in Table 1.

Experimental top

The 4-bromomethyl-2,6-di-tert-butyl-phenol was synthesized according to the method described by Rieker et al. (1968). N-methylaniline (3.21 g, 0.03 mol) and 4-bromomethyl-2,6-di-tert-butyl-phenol (9.0 g, 0.03 mol) were added, with stirring to THF(40 ml) at 278 K. The reaction mixture was stirred at 278–283 K for a further 2 h. then a solution of Na2CO3(1.60 g, 0.015 mol) in water (10 ml) was added. The solvent THF was evaporated under reduced pressure and the product was extracted by diethyl ether. The product (7.95 g) was obtained in a yield of 81.4%. Suitable crystals were obtained by slow evaporation of a mixture of ethyl acetate and methanol.

Refinement top

The phenyl goups of amines were disordered in tow positions with occupy fators 0.605 (10)/0.395 (10) and 0.621 (10)/0.379 (10) respectively. The disordered phenyl groups were constrained to a hexagon with the C—C distances 1.39 A. The H atoms of O—H were restrained on their parent atoms with O—H restrained 0.83 and 0.84Å at positions based on difference map peaks close to the parent O atoms.. 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).

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.
