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 A direct synthesis of alkenyl alkylidene bicyclo[3.1.0]hexane derivatives via ruthenium(II)-catalyzed bicyclization of allenynes, published in 2008-01-22, which mentions a compound: 92390-26-6, mainly applied to methylenecyclopropane preparation; cyclopropane methylene preparation; alkylidenebicyclohexane trimethylsilylethenyl preparation; bicyclohexane alkylidene trimethylsilylethenyl preparation; ruthenium catalyst bicyclization allenyne diazomethane, Quality Control of Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium.
The reaction of allenynes with N2CHSiMe3 in the presence of RuCl(cod)Cp* catalyst at room temperature constitutes a selective, general route to alkylidenebicyclo[3.1.0]hexanes having an adjacent Z-CH=CHSiMe3 group. E.g., reaction of allenyne CHCCH2NTsCH2CH:C:CMe2 with N2CHSiMe3 gave 52% alkylidenebicyclo[3.1.0]hexane I with a Z-CH=CHSiMe3 group. The reaction shows that the RuCl(Cp*) moiety favors reductive elimination of a metallacyclobutane intermediate and not the enyne metathesis process.
This literature about this compound(92390-26-6)Quality Control of Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)rutheniumhas given us a lot of inspiration, and I hope that the research on this compound(Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium) can be further advanced. Maybe we can get more compounds in a similar way.
