Bimetallic nickel aluminum mediated para-selective alkenylation of pyridine: direct observation of eta2,eta1-pyridine Ni(0)-Al(III) intermediates prior to C-H bond activation.

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 nickel aluminum complex prior to its C-H activation, which serves as key evidence for bimetallic catalysis.
