Li, Liping published the artcileExperimental and Computational Studies on Cp*CyRh(III)/KOPiv-Catalyzed Intramolecular Dehydrogenative Cross-Couplings for Building Eight-Membered Sultam/Lactam Frameworks, Recommanded Product: 2-Aminobenzonitrile(Flakes or Chunks), the main research area is dibenzothiazocine dioxide dibenzoazocinone preparation stereoselective chemoselective regioselective rhodium catalyst; vinyl aryl amide Intramol dehydrogenative cross coupling; benzamide witting reaction vinyl aniline preparation.
Described herein is an unusual Cp*CyRh(III)-catalyzed intramol. site-specific aryl C-H annulation, a highly chemoselective protocol providing direct access to eight-membered sultams/lactams I (R1 = H, 9-Me, 7-Cl, etc; R2 = Me, Et, Ph, 4-Br-C6H4; R3 = H, 2-Me, 3-OMe, etc.)and II (X = CO, PO-Ph; Ar = Ph, 2-Me-C6H4, Naph, Py, etc.) with broad substrate/functional group tolerance. Exptl. and computational studies reveal that such a transformation involves a unique PivOH-assisted aryl C-H activation/alkene insertion/β-H elimination/hydrogen-transfer process involving the Rh(III)-hydride species as the active intermediate with the concomitant release of H2 as the major byproduct, thus enabling the developed Cp*CyRh(III) catalysis with redox-neutral and highly atom-economical features.
