Metal-Free Cross-Coupling of Arylboronic Acids and Derivatives with DAST-Type Reagents for Direct Access to Diverse Aromatic Sulfinamides and Sulfonamides.

We have developed a simple and convenient method for the cross-coupling of arylboronic acids and their derivatives with DAST-type reagents under mild and metal-free conditions to directly afford sulfinamides in moderate to good yields. Moreover, sulfonamides were obtained after a simple oxidation reaction. The reaction mechanism was investigated by (18) O-labeling experiments, and the synthetic utility was demonstrated by the sulfoxidation of natural products.
