Site-Selectivity of C(sp<sup>2</sup>)–H Oxidative Addition of Fluorinated Arenes with Pyridine(dicarbene) Cobalt(I) Complexes and Aryl Isomerization

The rate, site-selectivity, and product isomerization of the C(sp<sup>2</sup>)–H oxidative addition of arenes with pyridine(dicarbene) cobalt methyl and phenyl complexes have been investigated with four representative arenes of varying electronic and steric properties. The rates of C(sp&...
