STREM Chemicals, Inc. Licenses New Class of Air-Stable Ni(0) Pre-Catalysts from Max-Planck-Institut für Kohlenforschung
STREM Chemicals, Inc. has licensed a technology based on recent developments in the field of Ni(0) (pre)catalysts from the Max-Planck-Institut für Kohlenforschung respectively the associated Studiengesellschaft Kohle mbH. The new Ni(0)-olefin pre-catalyst provides a simple, scalable, and modular Ni(0) source which is stable to air and room temperature and retains the reactivity demonstrated by Ni(0) catalysts currently used in organic chemistry and industrially relevant transformations. 
The history of Ni(0) complexes and their reactivity with olefins are tightly connected to the Max-Planck-Institut für Kohlenforschung, and date back to the mid-last century, with the serendipitous discovery of the so-called “nickel effect”. At that time, the team of Professor Karl Ziegler (director of the Institute) was working on the polymerization of ethylene to produce a-olefins using Al-based compounds; the well-studied Aufbaureaktion was set up in an autoclave with triethylaluminium and ethylene to obtain the expected mixture of higher-order chain-lengths aluminum alkyls. Suddenly, in a routine experiment, the reaction took an unexpected course, giving a quantitative yield of 1-butene and unchanged triethylaluminium. After several attempts to elucidate the origin of such side reactivity, the scientists concluded that this was the result of traces of nickel left from the wall of the autoclave. This finding opened up a new branch of chemistry and led to the discovery of the “Ziegler catalysis”, a reaction of central importance for the industrial production of polymers. Professor Günther Wilke succeeded Professor Ziegler as director of the same institute and, together with his team, further unfold the field of nickel catalysis. His studies on the use of the Ziegler catalysts for the polymerization of butadiene established the basis for the development of the bis(1,5-cyclooctadiene)Ni(0) (Ni(COD)
