Synthesis of Allenamides by Copper-Catalyzed Coupling of Propargylic Bromides and Nitrogen Nucleophiles.
An efficient and general synthesis of allenamides derived from oxazolidinones and hydantoins is reported, and propargylic bromides were found to be suitable reagents for the direct allenylation of nitrogen nucleophiles by a formal copper-catalyzed S(N)2' reaction. Expand

The copper-promoted S-cyclopropylation of thiophenols using cyclopropylboronic acid is reported, and the reaction tolerates substitution in ortho-, meta- and para-substitution as well as electron-donating and electron-withdrawing groups. Expand
Palladium-Catalyzed Carbonylative Cross-Coupling Reaction between Aryl(Heteroaryl) Iodides and Tricyclopropylbismuth: Expedient Access to Aryl Cyclopropylketones
The carbonylative cross-coupling reaction between aryl and heteroaryl iodides and tricyclopropylbismuth is reported. The reaction is catalyzed by (SIPr)Pd(allyl)Cl, a NHC-palladium(II) catalyst,… Expand
First use of an organobismuth reagent in C(sp3)–S bond formation: Access to aryl cyclopropyl sulfides via copper-catalyzed S–Cyclopropylation of thiophenols using tricyclopropylbismuth
Abstract The direct S-cyclopropylation of thiophenols using tricyclopropylbismuth is reported. The reaction is catalyzed by copper(II) acetate and operates under mild conditions to afford the… Expand
