Abstract

Functionalisation in 2 position of benzenes 1, 3-disubstituted by para-directing groups has been investigated, involving 2-trimethylsilylated intermediates when the classical methods (particularly these involving the anion in 2 position) are ineffective. Thus 2-trimethylsilyl derivatives of 1, 3-dihalo-or 1, 3-dimethoxybenzene have been prepared in good yields. Their conversion into the corresponding 1, 2, 3-trisubstituted benzenes has been ...
