ABSTRACT
Irradiation of [Ru(GaCp*)3(SiEt3)H3] (1) at 350 nm induces reductive elimination of dihydrogen and triethylsilane and generates unsaturated Ru/Ga species. This photochemically induced cascading reductive elimination processes generate the reactive intermediate [Ru(GaCp*)3], which can be trapped by diphosphine coordination to yield the stable complex [(dppe)Ru(GaCp*)3] (4). The photochemically generated RuGa3 species is catalytically active in the hydrogenation of alkynes, which is further investigated by 1H NMR and mass spectrometry. Formation of intermetallic Ru/Ga clusters is observed as a competing and for the catalytic activity of the species limiting side reaction.
