Hydroxoiridium-Catalyzed Hydroarylation of Alkynes and Bicycloalkenes with N-Sulfonylbenzamides.

Hydroxoiridium complexes efficiently catalyzed the hydroarylation of alkynes and bicycloalkenes with N-sulfonylbenzamides via C-H activation to give the corresponding ortho-alkenylation and alkylation products in high yields.

Selective H/D Exchange at Vinyl and Methylidene Groups with D2O Catalyzed by an Iridium Complex.

Selective H/D exchange at vinyl and methylidene groups of alkenes with D2O was promoted by an iridium catalyst generated in situ from a hydroxoiridium complex and N-mesylbenzamide.

Asymmetric Alkylation of N-Sulfonylbenzamides with Vinyl Ethers via C-H Bond Activation Catalyzed by Hydroxoiridium/Chiral Diene Complexes.

Asymmetric alkylation of N-sulfonylbenzamides with vinyl ethers via a directed C-H bond activation gave high yields of the corresponding addition products with high branch- and enantioselectivity.

Hydroxoiridium/Chiral Diene Complexes as Effective Catalysts for Asymmetric Annulation of α-Oxo- and Iminocarboxamides with 1,3-Dienes.

The asymmetric [3+2] annulation of α-oxo- and α-iminocarboxamides with 1,3-dienes catalyzed by hydroxoiridium/chiral diene complexes was realized, giving high yields of the corresponding γ-lactams with high enantioselectivity.
