Yamamoto, Yoshihiko; Ogawa, Ryuji; Itoh, Kenji published the article 《Highly chemo- and regio-selective [2+2+2]cycloaddition of unsymmetrical 1,6-diynes with terminal alkynes catalyzed by Cp*Ru(cod)Cl under mild conditions》. Keywords: cycloaddition alkadiyne alkene ruthenium catalyst.They researched the compound: Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium( cas:92390-26-6 ).Name: Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:92390-26-6) here.
The title complex catalyzed the cycloaddition of 1,6-diynes with terminal alkenes to give indanes at room temperature or below. Satisfactory chemoselectivity was achieved using 2 equivalent of monoalkyne. Unsym. alkynes reacted with excellent meta-selectivity.
《Highly chemo- and regio-selective [2+2+2]cycloaddition of unsymmetrical 1,6-diynes with terminal alkynes catalyzed by Cp*Ru(cod)Cl under mild conditions》 provides a strategy for the preparation of materials with excellent comprehensive properties, which is conducive to broaden the application field of this compound(Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium)Name: Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium.
