Journal ArticleDOI
Improved Ruthenium Catalysts for Z-Selective Olefin Metathesis
TL;DR: Several new C-H-activated ruthenium catalysts for Z-selective olefin metathesis have been synthesized and, with these catalysts, turnover numbers approaching 1000 were possible for a variety of cross-metathesis reactions, including the synthesis of industrially relevant products.
Journal ArticleDOI
Cyclic alkyl amino carbene (CAAC) ruthenium complexes as remarkably active catalysts for ethenolysis
Vanessa M. Marx,Alexandra H. Sullivan,Mohand Melaimi,Scott C. Virgil,Benjamin K. Keitz,David S. Weinberger,Guy Bertrand,Robert H. Grubbs +7 more
TL;DR: This is the first time a series of metathesis catalysts has exhibited such high performance in cross-metathesis reactions employing ethylene gas, with activities sufficient to render ethenolysis applicable to the industrial-scale production of linear α-olefins (LAOs) and other terminal-olefin products.
Journal ArticleDOI
Z-Selectivity in Olefin Metathesis with Chelated Ru Catalysts:Computational Studies of Mechanism and Selectivity
Peng Liu,Xiufang Xu,Xiufang Xu,Xiaofei Dong,Benjamin K. Keitz,Myles B. Herbert,Robert H. Grubbs,Kendall N. Houk +7 more
TL;DR: The mechanism and origins of Z-selectivity in olefin metathesis with chelated Ru catalysts were explored using density functional theory to show how Steric repulsions between the substituents on the oleFin and the N-substituent on theN-heterocyclic carbene ligand lead to highly selective formation of the Z product.
Journal ArticleDOI
Olsalazine-Based Metal-Organic Frameworks as Biocompatible Platforms for H2 Adsorption and Drug Delivery.
Dana J. Levine,Tomče Runčevski,Matthew T. Kapelewski,Benjamin K. Keitz,Julia Oktawiec,Douglas A. Reed,Jarad A. Mason,Henry Z. H. Jiang,Kristen A. Colwell,Christina M. Legendre,Stephen A. FitzGerald,Jeffrey R. Long +11 more
TL;DR: The low toxicity, high surface areas, and coordinatively unsaturated metal sites make these M2(olz) materials promising for a range of potential applications, including drug delivery in the treatment of gastrointestinal diseases.
Journal ArticleDOI
A spin transition mechanism for cooperative adsorption in metal–organic frameworks
Douglas A. Reed,Benjamin K. Keitz,Benjamin K. Keitz,Julia Oktawiec,Jarad A. Mason,Tomče Runčevski,Tomče Runčevski,Dianne J. Xiao,Lucy E. Darago,Valentina Crocellà,Silvia Bordiga,Jeffrey R. Long,Jeffrey R. Long +12 more
TL;DR: The electronic basis for the cooperative adsorption demonstrated here could provide a general strategy for designing efficient and selective adsorbents suitable for various separations.
