METALATION REACTIONS. IX. DILITHIATION OF AROMATIC THIOETHERS

Article abstract of DOI:10.1016/S0040-4039(00)85022-4

Direct dimetalation of aromatic thioethers gives with good yield the dilithiated species 3, 4, 17, 18, 25, 26.The first four species allowed the simultaneous introduction of an electrophile in the thiomethyl group and in the ring, while the last two species undergo disubstitution in the ring.
