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 functionalized dienes from propargylic esters: formal cross-coupling of two carbenes, published in 2009, which mentions a compound: 92390-26-6, mainly applied to conjugated diene stereoselective synthesis; Ruthenium catalyzed cross coupling diazoalkane carbene propargylic ester, Name: Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium.
The coupling of a propargylic ester with a diazoalkane in the presence of [RuCl(cod)Cp*] catalyst leads to the formation of functionalized conjugated dienes with high stereoselectivity. The reaction involves the cross-coupling of a vinylcarbene fragment, arising from a ruthenium-catalyzed propargylic ester rearrangement, with a diazoalkane carbene.
Here is a brief introduction to this compound(92390-26-6)Name: Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium, if you want to know about other compounds related to this compound(92390-26-6), you can read my other articles.
