Journal ArticleDOI
Uranium−Nitrogen Multiple Bonding: The Case of a Four-Coordinate Uranium(VI) Nitridoborate Complex
TL;DR: Bond multiplicities based on Nalewajski-Mrozek valence indices suggest that the UN(nitrido) interaction in 3 is close to a full triple bond.
Journal ArticleDOI
Dinitrogen Cleavage Stemming from a Heterodinuclear Niobium/Molybdenum N2 Complex: New Nitridoniobium Systems Including a Niobazene Cyclic Trimer
Daniel J. Mindiola,Karsten Meyer,John-Paul F. Cherry,and Thomas A. Baker,Christopher C. Cummins +4 more
TL;DR: In this paper, the terminal nitrido anion and the niobazene trimer were preprocessed for cooperative splitting of dinitrogen upon reduction of the heterobimetallic paramagnetic DIN complex (Ar[R]N)3Mo(μ-N2)Nb(N[iPr]Ar)3 (R = tBu or C(CD3)2 CH3).
Journal ArticleDOI
A Cyclometalated Resting State for a Reactive Molybdenum Amide: Favorable Consequences of β-Hydrogen Elimination Including Reductive Cleavage, Coupling, and Complexation
Yi-Chou Tsai,Marc J. A. Johnson,Daniel J. Mindiola,Christopher C. Cummins,Wim T. Klooster,Thomas F. Koetzle +5 more
TL;DR: In this article, it was shown that the cyclometalated triplescorebond of molybdenum(III) by N-isopropylanilide gives rise to the metallaziridine derivative Mo(H)(H)({eta}{sup 2}-Me{sub 3}C{double{underscore}bond}NAr)(N[{sup i}Pr]Ar){sub 2} (1, Ar = 3,5-C{sub 6}H{sub 4}Me{Sub 3}Me
Journal ArticleDOI
Redox-Catalyzed Binding of Dinitrogen by Molybdenum N-tert-Hydrocarbylanilide Complexes: Implications for Dinitrogen Functionalization and Reductive Cleavage
Jonas C. Peters,John-Paul F. Cherry,J. Christopher Thomas,Luis M. Baraldo,Daniel J. Mindiola,William M. Davis,Christopher C. Cummins +6 more
TL;DR: In this paper, it was shown that the function of sodium amalgam in this system is as a redox catalyst, accelerating the conversion of Mo(N[R]Ar)_3 to (μ-N2 )-bridged complex.
Journal ArticleDOI
On the origin of selective nitrous oxide N-N bond cleavage by three-coordinate molybdenum(III) complexes.

TL;DR: Stopped-flow kinetic measurements revealed the reaction to be first order in both Mo(N[R]Ar)(3) and N(2)O, consistent with a mechanism featuring post-rate-determining dinuclear N-N bond scission, but also consistent with cleavage of the N- N bond at a single metal center in a mechanism requiring the intermediacy of nitric oxide.
