The research and development of new reagents are of great significance for organic synthesis. In recent years, some new reagents with universal applicability have been constantly emerging. This article introduces the latest research progress on new reagents for difluoromethylation and trifluoromethylation. Introduced some new sulfur-containing reagents. New reagents DMSO-I₂ and DMSO-TsCl for sulfur methylation were introduced detailedly, The sulfur-containing reagent Na₂S₂O₄-TBHP (TBHP, t-butylhydroperoxide) is a new reagent used for selective oxidation of aromatic alcohols to aldehydes which was also known as Wang's reagent.
