Asymmetric olefin metathesis

It hydrolyzes violently upon contact with water and easily disproportionates to form a mixture of lower ruthenium fluorides, releasing fluorine gas. Ruthenium pentafluoride is a tetrameric dark green solid that is also readily hydrolyzed, melting at The yellow ruthenium tetrafluoride is probably also polymeric and can be formed by reducing the pentafluoride with iodine.

Hydrosilylation Catalyst in Chemical Synthesis. Vinylsilanes are versatile organometallic reagents that participate in a variety of reaction paradigms such as Tamao–Fleming oxidation, olefin metathesis, Pd-catalyzed cross-coupling, protodesilylati. In organic chemistry, an alkene is an unsaturated hydrocarbon that contains at least one carbon–carbon double bond. The words alkene and olefin are often used interchangeably (see nomenclature section below). Acyclic alkenes, with only one double bond and no other functional groups, known as mono-enes, form a homologous series of hydrocarbons with the general formula C n H 2n. Catalytic asymmetric ring-opening metathesis (AROM) provides an efficient method for the synthesis of a variety of optically enriched small organic molecules that cannot be easily prepared by alternative methods.
