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).
