Osaka, Japan \u2013 The chemical industry commonly uses rare, expensive metals to produce pharmaceuticals and other essential substances. Replacing these metals whenever possible with more-abundant, cheaper substitutes would benefit environmental sustainability, lower costs, and minimize the risk of supply chain disruptions.<\/p>\n

Now, in a study recently published in Chemistry \u2013 A European Journal<\/em>, researchers from Osaka University and collaborating partners have met this need in their work on an industrially useful chemical transformation. The simple, gentle reaction conditions reported here might inspire researchers who are working to reduce use of expensive metals for as many chemical reactions as possible.<\/p>\n

So-called noble metals are especially versatile materials. For example, palladium is a metal of choice for catalyzing a chemical transformation \u2013 converting nitriles into primary amines \u2013 that is a common step in nylon and plastics production. However, such metals are rare and costly. Substitutes based on common metals such as nickel could be cheaper catalysts. Unfortunately, many cheap metals require challenging experimental conditions, such as high pressures and temperatures, for the previously mentioned chemical transformation. Determining whether nickel carbide has the same limitations \u2013 and if not, evaluating the scope of the chemical transformations that are possible with this catalyst \u2013 was the goal of the research team\u2019s study.<\/p>\n

\u201cIn our work, we thoroughly study the reaction chemistry that underlies a novel nickel carbide nanoparticle heterogeneous catalyst for selective hydrogenation of nitriles into primary amines,\u201d explains Sho Yamaguchi, lead author of the study. \u201cThe substrate scope is broad \u2013 many types of heteroaromatic and aliphatic nitriles can undergo this transformation.\u201d<\/p>\n

There are several advantages of the researchers\u2019 catalyst. One, despite the mild required reaction conditions \u2013 1 atmosphere pressure of hydrogen and a relatively low temperature of approximately 150\u00b0C \u2013 the catalyst still exhibited 4-times the activity of simple nickel nanoparticles. Two, the catalyst was reusable: at least 3-times. Three, the reaction yields were high: up to 99%.<\/p>\n

\u201cWe\u2019re excited because our research will help minimize the use of expensive metals for and simplifies the experimental setup of a common class of chemical syntheses,\u201d says Tomoo Mizugaki, senior author. \u201cFurthermore, our theoretical calculations provide insights that will help us optimize the catalyst for additional applications.\u201d<\/p>\n

This work is an important step forward in increasing the sustainability of a class of chemical reactions that are required for synthesizing pharmaceuticals and many other everyday products. Because the nickel catalyst is much cheaper than a noble metal, and the required experimental procedures are simple, feasible applications to further chemical transformations should be straightforward.<\/p>\n
