On the ethenolysis of end-of-life tire granulates

End-of-life tire granulates were used in olefin metathesis reactions with ethene (ethenolysis); utilizing 0.0074 mmol of a Grubbs type ruthenium complex for 1.0 gram of tire granules leads to the isolation of ca. 0.5 g of organic solubles, which are primarily composed of oligomeric 1,4-cis isoprenes.
