  Palladium-Catalyzed Cs₂CO₃-Promoted Arylation of Unactivated C(sp³)–H Bonds by (Diacetoxyiodo)arenes: Shifting the Reactivity of (Diacetoxyiodo)arenes from Acetoxylation to Arylation

  摘要：

  PdCl2(CH3CN)(2)-catalyzed arylation of unactivated C(sp(3))-H bonds using (diacetoxyiodo)arenes as arylation reagents is reported. The reactivity of (diacetoxyiodo)arenes as arylation reagents is enabled in the presence of Cs2CO3 under the reaction conditions. This arylation method is highly efficient and occurs without the use of silver salt. The reaction tolerates a broad substrate scope that was not demonstrated by other silver salt-free C(sp(3))-H bond arylation conditions. The synthetic utility of the method is further illustrated in the synthesis of the psychotropic drug phenibut. A detailed mechanism study has been conducted to understand the reaction pathway.

  A highly efficient protocol for the β-arylation of carboxylic amides by aryl iodides under PdCl2(CH3CN)2/CsOAc catalysis was developed. This method was found to tolerate a broad scope of substrates and was successfully employed in the preparation of a variety of β-aryl α-amino and γ-amino acid derivatives. The utility of this method was further illustrated in the synthesis of the psychotropic drug

  Palladium-catalyzed primary and secondary sp3 C–H bond arylation is reported. The method using diarylhyperiodonium salts as arylation reagents shows good functional group tolerance and proceeds under mild reaction conditions. The KIE experiments show that the C–H bond activation is the rate-determining step.
