摘要：

A cyclometalation reaction involving C-F bond activation at a cobalt(I) center with an aldazine-N atom as an anchoring group, for the first time, affords an ortho-chelated cobalt(III) complex, 1, containing a [C-Co-F] fragment. Under otherwise similar conditions, the first example of an organo cobalt(II) cyanide, 2, formed through Ar-CN bond activation could be obtained using the reaction of 2,6-difluorobenzonitrile with a cobalt(0) complex without C-F bond activation. Both 1 and 2 were characterized through X-ray diffraction.
