A new preparative method of aryl sulfonate esters by using cyclic organobismuth reagents
A new method for the preparation of aryl sulfonate esters by using a cyclic pentavalent bismuth is described. Aryl sulfonate esters are formed in good to high yields by treating 10-arylphenothiabismine 5,5-dioxides, m-chloroperoxybenzoicacid (m-CPBA)and various sulfonic acids in dichloromethane.
