Visible-Light Photoredox-Catalyzed Regioselective Sulfonylation of Alkenes Assisted by Oximes via [1,5]-H Migration
摘要:
We herein report a visible-light photoredox-catalyzed regioselective sulfonylation of alkenes with sulfonyl hydrazides assisted by oximes at room temperature, which affords a variety of sulfones in good yields. The initial mechanistic experiments demonstrate that the hydroxyl group within oximes plays a crucial role in this sulfonylation.
TBAI-catalyzed selective synthesis of sulfonamides and β-aryl sulfonyl enamines: coupling of arenesulfonyl chlorides and sodium sulfinates with <i>tert</i>-amines
A simple, practical and metal-free method has been developed for the synthesis of sulfonamides and β-arylsulfonyl enamines via the selective cleavage of C–N and C–H bonds through the iodine-catalyzed oxidation of arenesulfonyl chlorides and sodiumsulfinates with tert-amines. The method uses commercially available inexpensive catalysts and oxidants, and has a wide substrate scope and operational simplicity
