Abstract A new reaction was discovered: oxidative destruction of sulfides of ArSCH 2 CO 2 Me type to sulfonic acids ArSO 3 H effected by 70% HNO 3. This reaction was used to introduce an SO 3 H group instead of aromatic nitro group activated only by meta- substituents: At treating with HSCH 2 CO 2 Me+ K 2 CO 3 the NO 2 group was substituted to form ArSCH 2 CO 2 Me with subsequent transformation into ArSO 3 H. p- ...
