TpRu{P(pyr)3}(NCMe)Me initiates intermolecular C−H activation of benzene to form TpRu{P(pyr)3}(NCMe)Ph and, in the absence of benzene, intramolecular C−H activation of a pyrrolyl ring to form the cyclometalated species TpRu{κ2-P,C-P(pyr)2(NC4H3)}NCMe. TpRu{P(pyr)3}(NCMe)Ph catalyzes the hydrophenylation of ethylene in benzene to produce ethylbenzene in low yields. Experimental and computational analyses of the hydrophenylation of ethylene by TpRu{P(pyr)3}(NCMe)Ph suggest that inefficient catalysis is not due to difficulty in the C−H activation of benzene by the active catalyst species, but rather likely arises from the steric bulk of the tris-N-pyrrolyl phosphine ligand, which inhibits coordination of ethylene and thus thwarts C−C bond formation.}, number={23}, journal={ORGANOMETALLICS}, author={Foley, Nicholas A. and Lail, Marty and Gunnoe, T.

TpRu(PMe3)(NCMe)Ph initiates C-D activation of C6D6 at rates that are approximately 2-3 times more rapid than that for TpRu(CO)(NCMe)Ph (depending on substrate concentration); however, the catalytic hydrophenylation of ethylene using TpRu(PMe3)(NCMe)Ph is substantially less efficient than catalysis with TpRu(CO)(NCMe)Ph. For TpRu(PMe3)(NCMe)Ph, C-H activation of ethylene, to ultimately produce TpRu(PMe3)(eta3-C4H7), is found to kinetically compete with catalytic ethylene hydrophenylation. In THF solutions containing ethylene, TpRu(PMe3)(NCMe)Ph and TpRu(CO)(NCMe)Ph separately convert to TpRu(L)(eta3-C4H7) (L = PMe3 or CO, respectively) via initial Ru-mediated ethylene C-H activation.

For X = OH or NHPh, H/D exchange occurs at hydroxide and anilido ligands, respectively. For X = OH, OPh, Me, Ph, or NHPh, isotopic exchange occurs at the Tp 4-positions with only minimal deuterium incorporation at the Tp 3- or 5-positions or PMe3 ligands.
