Selective Metathesis of α-Olefins from Bio-Sourced Fischer–Tropsch Feeds Rouen, Mathieu Queval, Pierre Borré, Etienne Falivene, Laura Poater Teixidor, Albert Berthod, Mikaël Hugues, François Cavallo, Luigi Baslé, Olivier Olivier-Bourbigou, Hélène Mauduit, Marc Fischer-Tropsch, Procés Fischer-Tropsch process Isomerització Isomerization Metàtesi (Química) Metathesis (Chemistry) Alquens Alkenes The search for a low-cost process for the valorization of linear α-olefins combining high productivity and high selectivity is a longstanding goal for chemists. Herein, we report a soluble ruthenium olefin metathesis catalyst that performs the conversion of linear α-olefins to longer internal linear olefins with high selectivity (>99%) under neat conditions at low loadings (50 ppm) and without the need of expensive additives. This robust catalytic process allowed us to efficiently and selectively re-equilibrate the naphtha fraction (C5–C8) of a Fischer–Tropsch feed derived from non-petroleum resources to a higher-value product range (C9–C14), useful as detergent and plasticizer precursors This work was supported by the European Community through the seventh framework program (CP-FP 211468-2 EUMET, grant to M.R., L.F., and E.B.).
