We have presented new amino-NHC Ni-Al complex mediated para C-H bond activation for pyridine and quinolin, and isolated for the first time the intermediate structure of a bimetallic eta(2),eta(1)-pyridine pyridine nickel aluminum complex prior to its C-H activation, which serves as key evidence for bimetallic catalysis.
