Abstract: Treatment of [OsClH3(PPh3)3] with (E)-Ph2P(CH2)2CH=CH(CH2)2PPh2 produced [OsClH(PPh3){Ph2P(CH2)2CH=CH(CH2)2PPh2}], which reacted with HOTf to give the dihydrogen(olefin) complex [OsCl(H2)(PPh3){Ph2P(CH2)2CH=CH(CH2)2PPh2}]OTf. Treatment of the latter complex with H2 did not result in hydrogenation of the olefin double bond, but gave the (hydrido)dihydrogen complex [OsH(H2)(PPh3){Ph2P(CH2)2CH=CH(CH2)2PPh2}]OTf. A density functional theory study suggested that hydrogenation of the double bond in [OsCl(H2)(PPh3){Ph2P(CH2)2CH=CH(CH2)2PPh2}]OTf was thermodynamically feasible but kinetically unfavorable.
