Challenge for the metal-free metathesis of olefins – ChaMO

Submission summary

Olefin metathesis is a pivotal transformation in organic chemistry, with numerous applications both in academic research and industrial processes: synthesis of polymers, complex bioactive compounds, specialty chemicals, biofuels from feedstock, materials… This key transformation relies on metal-carbene complexes. Yet, many of the metals required for this purpose are critical raw materials due to the high demand but limited stock, hence high cost, associated with localized production within a minimum number of countries. Other issues of metal-carbene complexes are the robustness of the catalyst, undesired reactions (isomerization of the olefin, cyclopropanation), sometimes difficult reactions with electron-poor olefins or Lewis basic nitrogen-enriched olefins, and the contamination of end products by metal residues. While efforts are currently directed towards the development of catalysts based on first-row transition metal complexes, the search for metal-free catalytic alternatives has been almost completely overlooked, with only a handful of papers. In the ChaMO project, we wish to address this challenge, by developing main-group element-based catalysts for olefin metathesis.
