Multiple Tandem Catalysis: Facile Cycling between Hydrogenation and Metathesis Chemistry

Abstract

Tandem ROMP−hydrogenation via a single Ru precursor permits catalytic reduction of ROMP polymers under exceptionally mild, homogeneous conditions (1 atm of H2, 60 °C). Repeated catalyst cycling between metathesis and hydrogenation chemistry is effected in a one-pot procedure.
