Apeiron / ἄπειρον – Unlimited, Infinite, Boundless!

Apeiron’s core technology, catalytic olefin metathesis, is revolutionizing the way chemists synthesize organic molecules. From the discovery of metathesis in the industrial laboratories of the 1950s, to the Nobel Prize awarded in 2005, an understanding of its mechanisms and potentials has increased exponentially. The promise and revolution of olefin metathesis is now being fully integrated into real world commercial applications.  

Six years ago, a team of top scientists and entrepreneurs came together to found Apeiron Synthesis and bring this promise to global customers in the pharma, agrochemical, flavor & fragrance, petrochemical and polymer sectors.

Building on this mission, Apeiron is now transforming metathesis into a powerful tool for the efficient and clean creation of chemical architectures for commercial applications. Our strategic solutions provide industry with the tools to benefit from the revolution. 

Apeiron’s team aspires to work hand-in-hand with customers to help transform their chemistry and bring about a revolution in catalysis and synthesis for R&D pipelines and manufacturing processes. We seek to advance the frontiers of chemical transformation, creating efficient and cost-effective solutions for commercial applications.

Our product is invention and our roots run deep in science and discovery which are at the heart of our mission. Our measure of success is when we help make your manufacturing processes faster, cheaper and greener. 

From the high tech labs and old-world charms of Wroclaw, Poland to our North American site at the Cambridge Innovation Center – in the heart of the world’s preeminent life-sciences/pharma cluster of Cambridge, Massachusetts – we are ready to bring the solutions and science of chemical transformation and synthesis to you.




Olefin metathesis is a chemical reaction in which two carbon-carbon double bonds (olefins) join and exchange with one another, forming new olefinic products.

The story of olefin metathesis originates in the industrial laboratories of the mid-1950s when chemists at DuPont, Standard Oil and Phillips Petroleum reported seemingly novel transformations – disproportionation – of olefins. The Calderon group at Goodyear were the first who called this transformation olefin metathesis in 1967. Intriguing results received by these pioneers drew the attention of other researchers to the potential of this new class of reactions. 

Importantly, this transformation long remained a laboratory curiosity without significance for advanced organic chemistry until the early 1990s when a burgeoning interest in metathesis began in large part due to the development of well-defined homogeneous catalyst systems in combination with reaction scope studies in academic laboratories. 

Today we are witnessing the widespread application of metathesis reactions for synthesis within different sectors and product categories including pharmaceuticals, fragrance chemicals, pheromones, modified rubbers, lubricants, specialty surfactants, polymers and many others. By definition the formation of new (olefinic) products presents unique opportunities. Apeiron’s mission is to seize these opportunities and bring these innovations to you.


Apeiron’s Technology and Our Advantages

Apeiron's Technology

Apeiron’s technology which includes various ruthenium based catalysts can satisfy nearly any process utilizing metathesis and is ready to be applied both in R&D and production process. 

Specifically, our technology platform is highly modular, allowing us to manufacture various catalysts incorporating tailored structural modifications in the ionic, benzylidene and/or NHC moieties that best fit to structural requirements of metathesis substrate.  Above that we specialize in modifications of the NHC moiety that incorporate utility tags into this nonlabile ligand, which afford novel auxiliary traits and provide substantial advantages in practical syntheses. We combine the latest academic advancements with customer-driven product development.

Apeiron takes advantage of both proprietary technology that is the result of an in-house research program and external intellectual property licensed from leading European industrial and academic partners.
