Unexpected Dehydrogenation of a Cyclohexyl Group at Low Temerature through Protonation of RuH3(η5-C5Me5)(PCy3) (Cy = cyclohexyl). X Ray Structure of 5-C5Me5)Ru((C6H9)P(C6H11)2)>BF4

Low temperature protonation of RuH3(η₅-C5Me5)(PR3) (R = Prⁱ, Ph, cyclohexyl) leads either to decomposition (R = Prⁱ) to a mixture of cis- and trans-5-C5Me5)(PR3)2>BF4 (R = Ph), or to dehydrogenation of a cyclohexyl group to afford the complex 5-C5Me5)((C6H9)P(C6H11)2)>BF4 which shows a strong agostic interaction beween a C-H bond of the cyclohexyl group and the metal; a possible application of the later observation is proposed for the dehydrogenation of alkenes.
