phenyl ring attached to the nitrogen atom of the amidinate group, the C–H bond activation process was observed on the ortho position of the phenyl ring attached to the carbon atom of the amidinate group. This process can be proved by X-ray structural determination. The molecular structures are reported for compounds 1 and 4.
