Synthesis of vinylgermanes via the Au/TiO2-catalyzed cis-1,2-digermylation of alkynes and the regioselective hydrogermylation of allenes

In the presence of Au/TiO2 (1 mol %), terminal alkynes react quantitatively with stoichiometric amounts of the unactivated digermane Me3Ge-GeMe3, forming exclusively cis-1,2-digermylated alkenes. We also establish the Au/TiO2-catalyzed hydrogermylation of terminal allenes with Et3GeH, which exhibits a highly regioselective mode of addition on the more substituted double bond forming vinylgermanes. Additionally, we provide preliminary results regarding the Pd nanoparticle-catalyzed C-C coupling of 1,2-digermyl alkenes with aryl iodides.

Palladium-catalyzed desulfitative hydroarylation of alkynes with sodium sulfinates

A palladium-catalyzed desulfitative hydroarylation of alkynes with aryl sulfinic acid sodium salts is described. The reaction showed good regio- and stereoselectivity, and afforded the hydroarylation products in good yields. Various functional groups were well tolerated under the optimized reaction conditions.

Palladium-catalyzed double arylations of terminal olefins in acetic acid

A palladium-catalyzed Heck diarylation of terminal olefins under ligand-free conditions in acetic acid is described. This procedure allows double arylation of terminal olefins affording trisubstituted olefins in good to excellent yields. The methodology is applicable to the coupling of both electron-deficient and electron-rich aryl iodides leading to symmetrical and unsymmetrical β,β-diarylated alkenes.
