Application In Synthesis of Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium, is researched, Molecular C18H28ClRu, CAS is 92390-26-6, about Synthesis of multiply functionalized benzenes via ruthenium-catalyzed cycloaddition of diiododiynes.
Highly functionalized benzenes, e.g., I, were precisely synthesized via multi-step processes consisting of ruthenium-catalyzed [2+2+2] cycloaddition of diiododiynes with an ethynylboronate or terminal alkynes, and subsequent chemo- and regio-selective palladium-catalyzed C-C bond-forming reactions of the resulting cycloadducts. The sequential cycloaddition/coupling process was applied to the synthesis of oligo(p-phenylene ethynylene)s.
