Direct dimetalation of aromatic thioethers gives with good yield the dilithiated species , , , , , . 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.
芳硫醚的直接dimetalation给人以良好的产量二锂种,,,,,。前四个物种允许在硫代甲基基团和环中同时引入亲电试剂,而后两个物种在环中发生破坏。
