title: Iridium complex catalyzed germylative coupling reaction between alkynes and iodogermanes--a new route to alkynylgermanium and alkynylgermasilicon compounds.
abstract: The new reaction of terminal alkynes with iodogermanes proceeding in the presence of an Ir(I)-complex [{Ir(μ-Cl)(CO)2}2] (I) and NEt((i)Pr)2, as a hydrogen iodide acceptor, leads to the formation of functionalized alkynylgermanes. This reaction occurs via direct activation of the C(sp)-H bond in the starting alkyne. Detailed stoichiometric experiments using [Ir(cod)(CCPh)(PCy3)] (IVa) and iodogermane were performed and resulted in a proposal of a reasonable mechanism for the germylative coupling reaction between alkynes and iodogermanes.
