Autor: Jamie A. Cadge, Paul J. Gates, John F. Bower, Christopher A. Russell
Publikováno v: Cadge, J A, Gates, P J, Bower, J F & Russell, C A 2022, ' Migratory Insertion of CO into a Au-C Bond ', Journal of the American Chemical Society, vol. 144, no. 43, pp. 19719-19725 . https://doi.org/10.1021/jacs.2c10432
A MeDalPhos-ligated gold(III) metallafluorene complex, generated via C-C oxidative addition of biphenylene, reacts with CO to produce 9-fluorenone. Experimental and computational studies show that this proceeds via a hitherto unknown migratory insert

Cyclopropane-Fused N-Heterocycles via Aza-Heck-Triggered C(sp3)–H Functionalization Cascades
Autor: Changcheng Jing, Benjamin T. Jones, Ross J. Adams, John F. Bower
Publikováno v: Journal of the American Chemical Society
Unique examples of aza-Heck-based C(sp3)-H functionalization cascades are described. Under Pd(0)-catalyzed conditions, the aza-Heck-type cyclization of N-(pentafluorobenzoyloxy)carbamates generates alkyl-Pd(II) intermediates that effect C(sp3)-H pall

Carbonylative N-Heterocyclization via Nitrogen-Directed C–C Bond Activation of Nonactivated Cyclopropanes
Autor: Adam D. J. Calow, David Dailler, John F. Bower
Publikováno v: Journal of the American Chemical Society. 144:11069-11074
Under Rh-catalyzed conditions, secondary amines and anilines function as directing groups to facilitate regioselective C-C bond activation of nonactivated cyclopropanes. The resulting amino-stabilized rhodacycles undergo carbonylative C-N bond format

Synthesis of Nitrogen Heterocycles via Directed Carbonylative C–C Bond Activation of Cyclopropanes
Autor: Andrew G. Dalling, John F. Bower
Publikováno v: CHIMIA, Vol 72, Iss 9 (2018)
This review concentrates on recent developments from our laboratory concerning the Rh-catalyzed carbonylative C–C bond activation of cyclopropanes. Specifically, we have found that N-based directing groups are effective at controlling the regiosele

A Systematic Study of the Effects of Complex Structure on Aryl Iodide Oxidative Addition at Bipyridyl‐Ligated Gold(I) Centers
Autor: Jamie A. Cadge, Christopher A. Russell, John F. Bower
Publikováno v: Angewandte Chemie International Edition. 60:24976-24983
A combined theoretical and experimental approach has been used to study the unusual mechanism of oxidative addition of aryl iodides to [bipyAu(C2 H4 )]+ complexes. The modular nature of this system allowed a systematic assessment of the effects of co
