The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium(SMILESS: [Cl-][Ru+2]1234567(C8(C)=C4(C)[C-]5(C)C6(C)=C87C)[CH]9=[CH]1CC[CH]2=[CH]3CC9,cas:92390-26-6) is researched.SDS of cas: 27828-71-3. The article 《Ruthenium-Catalyzed [2 + 2] Cycloadditions of Bicyclic Alkenes with Alkynyl Phosphonates》 in relation to this compound, is published in Journal of Organic Chemistry. Let’s take a look at the latest research on this compound (cas:92390-26-6).
Ruthenium-catalyzed [2+2] cycloadditions of bicyclic alkenes with alkynyl phosphonates were investigated. The phosphonate moieties were compatible with the Ru-catalyzed cycloadditions giving the corresponding cyclobutene cycloadducts in low to excellent yield (up to 96%). Alkynyl phosphonates showed lower reactivity than other heteroatom-substituted alkynes such as alkynyl halides, ynamides, alkynyl sulfides, and alkynyl sulfones and required a higher reaction temperature and much longer reaction time.
In addition to the literature in the link below, there is a lot of literature about this compound(Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium)Application of 92390-26-6, illustrating the importance and wide applicability of this compound(92390-26-6).
