In other homogeneous (or heterogeneous) catalyst systems in which the metal is likely to be in a relatively high oxidation state, such as molybdenum (VI) or tungsten (VI), metal -
carbon multiple bonds may play an important role.
For example in octanes, such as the ones found in gasoline, there's a
carbon chain of eight
carbons with
multiple C - H
bonds with different chemical properties, Garcia - Bosch said, and from the oxidation of each of the C - H
bonds, a different product results.
