General description

Pentamethylcyclopentadienyltris (acetonitrile)ruthenium(II) hexafluorophosphate is an organoruthenium compound. It is used as a homogeneous catalyst in organic synthesis. It enables the hydrosilylation of alkynes, cyclotrimerization of alkynes, cycloaddition reactions, and carbon-carbon or carbon-heteroatom bond-forming reactions.

Application

Hydrosilylation Catalysts
A versatile catalyst for hydrosilylation of alkynes providing α-vinylsilanes.
Reagent use as catalyst precursors for carbon-carbon or carbon-heteroatom bond forming reactions.

The complex [Cp*Ru(MeCN)3]PF6 is shown to catalyze the hydrosilylation of a wide range of alkynes. Terminal alkynes afford access to alpha-vinylsilane products with good regioselectivity. Deuterium labeling studies indicate a clean trans addition process is at work. The same complex

Alkyne Hydrosilylation

Vinyl-metal reagents play a pivotal role in organic synthesis. Among the vinyl-metal reagents available, silicon-based reagents are of increasing importance. This is largely due to their low cost, minimal toxicity, ease of handling, and the simplicity of byproduct removal.

Hydrosilylation Catalyst

This robust protocol for hydrosilylation of terminal acetylenes to give α-vinylsilanes using [Cp*Ru(MeCN)3]PF6, as well as a number of other catalysts for hydrosilylation, comes from the Trost group at Stanford University.
