treatment with electrophiles provides a convenient approach to ortho-substituted arenethiol derivatives. The reactions with tetraisopropylthiuram disulfide provide direct access to the corresponding o-phenylene trithiocarbonates. Double lithiation of 4-methoxybenzenethiol results in C-lithiation adjacent to the methoxy group rather than the thiolate residue, indicating that methoxy is a more powerfully ortho-directing
