Abstract Herein, we report a metal and additive‐free unprecedented reactivity of β‐ketothioamides with sulfonyl chlorides for the synthesis previously unreported 2‐sulfonyl‐3‐oxo‐N,3‐diarylpropanamides via in situ thioamide to amide conversion followed by dehydrohalogenative C−S cross‐coupling at room temperature under an open air first time. The protocol demonstrates not only its operational simplicity, efficiency, mild condition, scalability, but also easy get diverse a‐sulfonyl‐β‐ketoamides good high yields. Additionally, DFT photophysical studies supported proposed mechanism, revealed unique excitation‐dependent emission coupled ESPT synthesized sulfones.
