Abstract
Reaction of methyl sulfinates with lithium amides followed oxidation of the resulting sulfinamides provides primary, secondary, and tertiary alkane-, arene- and heteroarenesulfonamides in high yields. This protocol avoids the use of hazardous, unstable, or volatile reagents and does not affect the configurational stability of the amines.
