Anwendungen

Diphenyl sulfoxide is a reagent used as an oxidant and hydroxyl activator in combination with a variety of electrophilic reagents. Efficient glycosidation of a phenyl thiosialoside donor with diphenyl sulfoxide and triflic anhydride in dichloromethane was reported. Direct glycosylations with 1-hydroxy glycosyl donors is made using trifluoromethanesulfonic anhydride and diphenyl sulfoxide. The preparation of triarylsulfonium halides was by the action of aryl Grignard reagents on diphenyl sulfoxide.

Bemerkungen

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents.
