Intermolecular Pummerer Coupling with Carbon Nucleophiles in Non‐Electrophilic Media

Abstract

Abstract A new Pummerer‐type C−C coupling protocol is introduced based on turbo‐organomagnesium amides, which unlike traditional Pummerer reactions, does not require strong electrophilic activators, engages a broad range of C(sp 3 )‐, C(sp 2 )‐, and C(sp)‐nucleophiles, and seamlessly integrates with C−H and C−X magnesiation. Given the central character of sulfur compounds in organic chemistry, this protocol allows access to unrelated carbonyls, olefins, organometallics, halides, and boronic esters through a single strategy.
