摘要：

The complexes TpRu{P(OCH2)(3)CEt}(L)R {L = PPh3 or NCMe; R = Cl, OTf (OTf = trifluoromethanesulfonate), or Ph; Tp = hydridotris(pyrazolyl)borate} and TpRu{P(OCH2)(3)CEt} (eta(3)-C3H4Me) were synthesized and isolated. TpRu{P(OCH2)(3)CEt}(NCMe)Ph was found to initiate C-H activation of benzene and to catalyze the hydrophenylation of ethylene to produce ethylbenzene. Ethylene C-H activation to ultimately produce TpRu{P(OCH2)(3)CEt}(eta(3)-C3H4Me) kinetically competes with the catalytic hydrophenylation of ethylene. Computational studies were undertaken on reactions in the proposed catalytic ethylene hydrophenylation cycle as well as key side reactions.
