Tosyl Chloride is a typical reagent in ...
WebIn organic chemistry, a toluenesulfonyl group (tosyl group, abbreviated Ts or Tos) is a univalent functional group with the chemical formula −SO 2 −C 6 H 4 −CH 3.It consists of a tolyl group, −C 6 H 4 −CH 3, joined to a sulfonyl group, −SO 2 −, with the open valence on sulfur.This group is usually derived from the compound tosyl chloride, CH 3 C 6 H 4 SO 2 … WebThus, alcohols can be converted to tosylates and mesylates which is a very good leaving group. Most common reagents for this are mesyl chloride, abbreviated MsCl and tosyl chloride, abbreviated TsCl. Alcohols are converted to alkyl tosylates by treatment with p-toluenesulfonyl chloride (TsCl) in the presence of pyridine.
