Halogenated dihydric phenols (hydroquinones and resorcinols) undergo halogen metal exchange with nBuLi/TMEDA/THF or ether (inverse addition) under sonication, thereby generating a C,O,O-trilithiated species which can be trapped with electrophiles.

The synthesis of methyl 4,7-dihydro-4,7-dioxobenzothiophene-2-carboxylate (20) based on the reaction of methyl mercaptoacetate with activated 1,4-benzoquinones is described.Methyl 4,7-dihydro-4,7-dioxo-5-hydroxybenzothiophene-2-carboxylate (24) and its corresponding methyl ether 26 were obtained through a Thiele-Winter acetoxylation on 20.On the basis of the properties of methyl 4,7-dihydro-4,7-dioxo-6-methoxybenzothiophene-2-carboxylate (21) obtained from 2,4,5-trimethoxybenzaldehyde (32), the structures of the products 24 and 26 are proposed.
