In contrast to the 1,3-isomer (see preceding entry), direct dilithiation with n-BuLi/TMEDA was successful, giving, with TMS chloride, the 2,5-disilyl derivative in 68% yield: J. Org. Chem., 49, 4657 (1984).

1,4-Dimethoxybenzene and its simple derivatives undergo anodic oxidation in methanol, to give bis-acetals of benzoquinones. For experimental details, see: Org. Synth. Coll., 6, 971 (1988). For a review of the chemistry of these bis-acetals and of the mono-acetals obtained by partial hydrolysis, see: Acc. Chem. Res., 16, 74 (1983).
