Oxidative addition and C–H activation chemistry with a PNP pincer-ligated cobalt complex

Autor: Crisita Carmen Hojilla Atienza, Scott P. Semproni, Paul J. Chirik

Publikováno v: Chem. Sci.. 5:1956-1960

The bis(phosphino)pyridine (PNP) cobalt(I) methyl complex, (iPrPNP)CoCH3 is a rich platform for the oxidative addition of non-polar reagents such as H2, the C–H bonds of arenes and terminal alkynes. Rare examples of hexacoordinate cobalt(III) compo

Synthesis, Electronic Structure, and Ethylene Polymerization Activity of Bis(imino)pyridine Cobalt Alkyl Cations

Autor: Paul J. Chirik, Emil B. Lobkovsky, Crisita Carmen Hojilla Atienza, Carsten Milsmann

Publikováno v: Angewandte Chemie. 123:8293-8297

A new spin on polymers: the title cations comprise low-spin Co(II) centers with neutral bis(imino)pyridine chelating ligands. These complexes serve as single-component ethylene polymerization catalysts and offer insight into the mechanism of chain gr

Photolysis and thermolysis of bis(imino)pyridine cobalt azides: C-H activation from putative cobalt nitrido complexes

Autor: Paul J. Chirik, Emil B. Lobkovsky, Amanda C. Bowman, Crisita Carmen Hojilla Atienza

Publikováno v: Journal of the American Chemical Society. 132(46)

A series of planar aryl-substituted bis(imino)pyridine cobalt azide complexes were prepared and evaluated as synthetic precursors for the corresponding cobalt nitrido compounds. Thermolysis or photolysis of two examples resulted in intramolecular C-H
