A novel method toward synthesis of sulfonamides and β-arylsulfonyl enamines has been developed via I2/TBHP mediated C–N and C–H bond cleavage of tertiaryamines, which features highly selective formation of two different target products depending on the reaction solvent. The experimental results reveal that H2O as the solvent could effectively achieve the C–N bond cleavage to produce sulfonamides due

A copper-catalyzed coupling reaction of sulfonyl chlorides with tertiaryamines via the oxidative C–N bond cleavage of tertiaryamines was developed. Sulfonamides were synthesized using this strategy in moderate to good yields. The reaction was applicable to various tertiaryamines, as well as sulfonyl chlorides.
This invention relates to methods for preparing halogenated amines.

Technology for generating especially important amide and peptide bonds from carboxylic acids and amines that avoids traditional coupling reagents is described. The 1-pot processes developed rely on thioester formation, neat, using a simple dithiocarbamate, and are safe and green, and rely on Nature-inspired thioesters that are then converted to the targeted functionality.
