Abstract
Cycloisomerization and ring closing metathesis of some alpha,omega -dienes were catalyzed by a cationic arene ruthenium chelate complex [Ru{eta (6):et a (1)-Ph(CH2)(3)OH}(PCy3)Cl]BF4 (1a) in the presence of triethylamine and p henylacetylene, respectively, as co-catalysts. Analogous catalyst systems e mploying arene ruthenium cations without the side arm alcohol functional gr oup showed lower efficiencies. (C) 2000 Elsevier Science B.V. All rights re served.
