Where does the catalyst for olefin metathesis come from?
The catalyst is derived from tungsten trioxide supported on silica and MgO. 1,5-Hexadiene and 1,9-decadiene, useful crosslinking agents and synthetic intermediates, are produced commercially by ethenolysis of 1,5-cyclooctadiene and cyclooctene. The catalyst is derived from Re 2 O 7 on alumina.

Why are compatible catalysts needed for tandem catalysis?
Matching compatible catalysts would eliminate the likelihood of a catalyst starving or saturating the system, which may cause the catalyst to decompose or generate unwanted side reactions. If side products were to be generated, it may be capable of interfering with the catalytic system.
