Organocatalytic stereoselective C–H diazenylation of active methylenes with arenediazonium salts
Herein, we report the unveiling of the first organocatalytic sp3 C–H diazenylation of active methylenes with arenediazonium salts under ambient conditions, affording diverse hydrazones. The reaction features mild and additive-free conditions, excellent regio- and chemoselectivity, the use of readily available substrate...
