Not only symmetrical, but also unsymmetrical α,α-diaryl allylic alcohols are employed as substrates in the title reaction. A number of arenes and even heteroarenes underwent radical 1,2-aryl migration (“neophyl rearrangement”) to produce α-aryl β-trifluoromethyl ketones. The preferential electron-deficient aryl groups over electron-rich ones supports mechanism, which was further confirmed by DFT calculations. As a service our authors readers, this journal provides supporting information...

Abstract Ring structures such as pyridine, cyclopentane or their combinations are important motifs in bioactive molecules. In contrast to previous cycloaddition reactions that necessitated a directly bonded initiating functional group, this work demonstrated novel through‐(hetero)arene radical transmission concept for selective activation of remote bond. An efficient, metal‐free and atom‐economical [3+2] between 4‐pyridinyl cyclopropanes alkenes alkynes has been developed modular synthesis...

The Rh(III)-catalyzed C-H functionalizations of benzamide derivatives with olefin were studied by DFT calculations to elucidate the divergent pathways controlled N-OR internal oxidants. For substrates N-OMe and N-OPiv oxidants, energy profiles for consecutive N-H deprotonation/C-H activation/olefin insertion sequences similar, different properties reactivities generated 7-membered rhodacycles predicted. When is involved, this intermediate generally unstable, olefination occurs easily via a...
