[RuHCl(PPh3)3] reacts with penta-1,4-diene in CD2Cl2, to give initially [(η3-C5H9)RuCl(PPh3)2]. Dehydrogenation by an excess of pentadiene produces [(η5-C5H7)RuCl(PPh3)2]. When acetone is used as the dehydrogenating agent, then the reaction proceeds further to yield [(η-C5H5)RuCl(PPh3)2]. This known compound was prepared quantitatively by refluxing [RuHCl(PPh3)3] and penta-1,4-diene in methyl ethyl
