A new and efficient route for the synthesis of alkynyl functionalized silicon derivatives
The iridium-based catalytic system, [Ir(mu-Cl)(CO)(2)}(2)]/NEt(i-Pr)(2), was examined in the coupling reaction of iodotrisubstituted silanes (R3SiI) with various terminal arylalkynes ((RC)-C-1 CH). Under optimum conditions, the process occurs very efficiently (in particular for Me3SiI and Me2PhSiI), giving exclusively the respective C-sp-silyl functionalized alkynes ((RC)-C-1 CSiR3). Additionally, this iridium-based catalytic system was successfully used for the preparation of selected bis(phenylethynyl) disubstituted silanes [(R2Si)-Si-2(C CPh)(2)] via coupling of phenylacetylene with appropriate diiodo-disubstituted silanes ((R2SiI2)-Si-2).

Synthesis of Functional Carbo-benzenes with Functional Properties: The C2 Tether Key
and electrochemical analyses vs DFT-calculated nuclear and electronic structures. For the sake of the discussion consistency, complementary experimental and computational results are disclosed in the dianilinyl series. Overall, it is shown that combined advances in strategy, protocols, and substrate scope of acetylenic synthesis remain crucial for the development of yet poorly explored but promising
