International Journal of COPD, 2006 Therapy with bronchodilators forms the pharmacologic foundation of the treatment of patients with COPD. Bronchodilators can significantly lessen dyspnea, increase airflow, improve quality of life, and enhance exercise performance. While bronchodilators decrease airway resistance and lessen dynamic hyperinflation in patients with COPD, they have not ...

Room Temperature Cu-Catalyzed Amination of Aryl Bromides Enabled by DFT-Guided Ligand Design [PDF]
, 2023 Ullman-type C–N coupling reactions represent an important alternative to well-established Pd-catalyzed approaches due to the differing reactivity and the lower cost of Cu.

, 2013 Direct synthesis of 1,1-disubstitued 1,3-butadienes has been efficiently realized from the cross-coupling of cyclopropylmethyl N-tosylhydrazones with aromatic bromides by means of PdCl2(MeCN)(2) as catalyst.

Nature Communications, 2016 Benzyl bromides can be activated for radical reactions by photocatalytic single electron transfer. Here the authors show thatN-heterocyclic carbenes are also capable of activating this pathway for nitrobenzyl bromides, and that the radical intermediates ...

Dual Nickel/Photoredox-Catalyzed Regio- and Enantioselective Alkenylation of Epoxides. [PDF]
Adv Sci (Weinh)Ni/photoredox‐catalyzed stereoconvergent cross‐electrophile coupling of racemic epoxides with alkenyl bromides is described, affording β‐alkenyl products with up to 95% ee, excellent E‐selectivity, and complete regiocontrol. These versatile intermediates enable diverse chiral synthons; mechanistic studies suggest a halide ring‐opening followed by ...
