Cycloisomerization and ring closing metathesis of some α,ω-dienes were catalyzed by a cationic arene ruthenium chelate complex [Ruη6:η1-Ph(CH2)3OH}(PCy3)Cl]BF4 (1a) in the presence of triethylamine and phenylacetylene, respectively, as co-catalysts. Analogous catalyst systems employing arene ruthenium cations without the side arm alcohol functional group showed lower efficiencies.
一些α,ω二烯的环异构和闭环复分解,通过阳离子芳烃钌螯合物配合物催化的[Ru η 6:η 1 -Ph(CH 2)3 OH}(PCY 3)CL] BF 4(1A)在三乙胺和苯乙炔分别作为助催化剂的存在。使用没有侧臂醇官能团的芳烃钌阳离子的类似催化剂体系显示出较低的效率。
