In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Ruthenium catalyzed synthesis of unsaturated acetals and aldehydes via C-C bond coupling of alkynes with allyl alcohol, published in 1994-11-21, which mentions a compound: 92390-26-6, mainly applied to ruthenium catalyst coupling alkyne allyl alc; unsaturated aldehyde acetal; phenylacetylene coupling allyl alc catalyst, Reference of Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium.
Terminal alkynes and allyl alc. are coupled, with carbon-carbon bond formation, in the presence of a RuIV(C5Me5) catalyst, to give γ,δ-unsaturated acetals and with [{RuCl(C5Me5)}4] or [RuCl(cod)(C5Me5)] preferentially to produce the branched γ,δ-unsaturated aldehyde. Thus, phenylacetylene and allyl alc. afforded unsaturated acetals CH2:CPhCH2CH2CH(OCH2CH:CH2)2 and PhCH:CHCH2CH2CH(OCH2CH:CH2)2 or the corresponding unsaturated aldehydes.
In some applications, this compound(92390-26-6)Reference of Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
