Material Flows of Polyurethane in the United States
Autor: Ethan T. Gallant, Jennifer B. Dunn, Troy R. Hawkins, Graham P. Abramo, Chao Liang, Yuri A. Marques, Paul A. Gillis, Ulises R. Gracida-Alvarez
Publikováno v: Environmental Science & Technology. 55:14215-14224
Today, polyurethanes are effectively not recycled and are made principally from nonrenewable, fossil-fuel-derived resources. This study provides the first high-resolution material flow analysis of polyurethane flows through the U.S. economy, tracking

TEMPO-Mediated Catalysis of the Sterically Hindered Hydrogen Atom Transfer Reaction between (C5Ph5)Cr(CO)3H and a Trityl Radical
Autor: Hagen Neugebauer, Andreas Hansen, Stefan Grimme, Thilina Gunasekara, Markus Bursch, Jack R. Norton, Graham P. Abramo
Publikováno v: Journal of the American Chemical Society. 141:1882-1886
We have demonstrated the ability of TEMPO to catalyze H· transfer from (C5Ph5)Cr(CO)3H to a trityl radical (tris(p-tert-butylphenyl)methyl radical). We have measured the rate constant and activatio...

Isotope Effects on Hydrogen Atom Transfer from Transition Metals to Carbon
Autor: Graham P. Abramo, and Brian P. Santora, Kathryn E. Darula, David L. Ramage, Jack R. Norton, Mikhail A. Rodkin
Publikováno v: Organometallics. 18:1106-1109
The isotope effect for transfer of a hydrogen/deuterium atom from HMn(CO)5/DMn(CO)5 to the monomeric trityl radical (p-tBu-C6H4)3C• (1) has been measured from −40 to +60 °C in toluene; the isotope effect for transfer from H2Os(CO)4/D2Os(CO)4 has

Kinetics and thermodynamics of H. transfer from (eta5-C5R5)Cr(CO)3H (R = Ph, Me, H) to methyl methacrylate and styrene
Autor: Lihao Tang, Mu-Hyun Baik, Jack R. Norton, Anthony K. Rappé, Graham P. Abramo, Elizabeth T. Papish, Richard A. Friesner
Publikováno v: Journal of the American Chemical Society. 125(33)
The rates of H/D exchange have been measured between (a) the activated olefins methyl methacrylate-d(5) and styrene-d(8), and (b) the Cr hydrides (eta(5)-C(5)Ph(5))Cr(CO)(3)H (2a), (eta(5)-C(5)Me(5))Cr(CO)(3)H (2b), and (eta(5)-C(5)H(5))Cr(CO)(3)H (2

Polynuclear Catalysis: Enhancement of Enchainment Cooperativity between Different Single-Site Olefin Polymerization Catalysts by Ion Pairing with a Binuclear Cocatalyst
Autor: Liting Li, Graham P. Abramo, Tobin J. Marks
Publikováno v: Journal of the American Chemical Society. 124:13966-13967
A new multicenter ethylene polymerization process is described whereby two different single-site catalysts, one competent for producing vinyl-terminated oligomers or macromonomers and one competent for producing high-molecular weight ethylene-alpha-o
