Hydrosilylation of 1-hexyne promoted by acetone solvated gold atoms derived catalysts

Transition metals in organic synthesis: Highlights for the year 2005

“…A trans-selective hydrosilylation of alkynes catalyzed by ruthenium was reported [882]. Platinum [883] and gold [884] catalyzed cis-hydrosilylations of terminal alkynes adding the silicon to the terminal carbon. Palladium catalyzed an intramolecular bis-silylation of disilanyl allylic ethers (Eq.…”

Organic Synthesis Catalyzed by Supported Gold Nanoparticles

“…In 2005, Caporusso and coworkers reported the hydrosilylation of 1-hexyne with almost 100% selectivity by using carbon-or Al 2 O 3 -supported Au nanoparticles. 105 Subsequently, a great range of alkynes were tested by using different supported gold catalysts, which showed high selectivity comparable with that observed with homogeneous catalysts. In 2013, unsupported nanoporous gold has been used as catalyst in the hydrosilylation of phenylacetylene and other alkynes.…”

Panning for gold in a hot flowing stream

“…Gold-catalysed hydrosilylation (Fig. 3, panel a) has been shown to be catalysed by Au(III) complexes and supported Au nanoparticles; interestingly, given the results above, metallic gold has been reported to be catalytically inactive in this process (22,23). Li and coworkers have provided a mechanism for the Au-mediated addition of alkynes to imines that involves the formation of a terminal alkynyl-gold species (24).…”
