Gair, Joseph J. published the artcileSynthesis, Characterization, and Theoretical Investigation of a Transition State Analogue for Proton Transfer during C-H Activation by a Rhodium-Pincer Complex, COA of Formula: C23H43NP2, the publication is Organometallics (2019), 38(7), 1407-1412, database is CAplus.
A heterobimetallic Rh-pincer complex bearing a phenylzinc ligand was synthesized and characterized by multinuclear NMR, COSY, NOESY, and x-ray crystallog. The crystal structure of this complex shows that it possesses a bridging Rh-Zn-C fragment with a geometry similar to the Rh-H-C fragment in a proposed transition state for metal to ligand proton transfer during redox-neutral C-H activation with dearomatized Rh pincer complexes. Bonding anal. indicates that these fragments are isolobal, suggesting that the transition state analog models not only the structure but also the bonding interactions that underlie metal-ligand cooperativity in the C-H activation transition state. The similarity of the transition state and its analog prompted reevaluation of the relevant rate equations to determine the relative contributions of viable proton transfer pathways. Parallel anal. of the transition state and its isolobal analog thus serves as a bridge between theory and experiment that is rarely available in studies of bonding in transition states.
