The reaction of cyclooctatetraene with [RuCl(H)(PPh3)3]

Abstract

It has been shown that [RuCl(H)(PPh₃)₃] reacts with cyclooctatetraene to give three isomers, which are characterised by ¹H, ¹³C and ³¹P NMR spectroscopy to be two isomers of [Ru(η⁵-C₈H₉)Cl(PPh₃)₂] and {(2,3,4,5,6-η)-bicyclo[5.1.0]octadienyl}chlorobis(triphenylphosphine)ruthenium(II). The interconversion of the two isomers of the (1,2,3,4,5-η)-C₈H₉ derivative and the generation of an apparent plane of symmetry by exchange in the bicyclo[5.1.0]octadienyl derivative has been investigated quantitatively.
