Applications of the (PhO)3PCl2 Reagent: A New Protocol for Mild Cleavage of Sulfinamides and Sulfonamides
摘要:
The triphenyl phosphite-chlorine reagent, freshly in situ prepared by the action of chlorine on a solution of triphenyl phosphite in dichloromethane, is successfully used in the cleavage of both sulfonamides and sulfonamides under extremely mild conditions (-15 degrees C to r.t.). Final amines are easily recovered by a simple acid/base extraction, and no further purification is required.
