1,4-Bis(1,1-dimethylproyl)-2,5-dimethoxybenzene

Abstract

The title compound, C 18H 30O 2, was prepared by Friedel-Crafts alkylation of 1,4-dimethoxybenzene with 2-methyl-2-butanol. The complete molecule is generated by the application of a crystallographic centre of inversion. The two meth-oxy groups are oriented in the same plane of the aromatic ring [C-C-O-C torsion angle = 9.14 (16)°]. While one methyl group of the tert-pentyl substituent is coplanar with the benzene ring [C-C-C-C = 0.45 (15)°] and lies towards the less-hindered H atom, the other methyl and ethyl groups are directed to either side of the benzene ring [C-C-C-C torsion angles = 118.78 (12) and 59.11 (14)°, respectively]. In the crystal, the hydrophobic molecules pack to form a brick-wall-like architecture.
