Lewis Acid/Hydrogen Bonding Cooperative Catalysis. 178... [Pg.161]

Beyond the concept of combined acid catalysis, there are also many other bifunctional acid catalysts interacting with nucleophiles and electrophiles simultaneously, and thus benefiting through such cooperative effect. Selected examples on Lewis acid/hydrogen bonding cooperative catalysis and Lewis acid/transition-metal... [Pg.162]

The catalytic effect of Ir4(CO)i2 on the methanation reaction is notoriously enhanced by the presence of strong Lewis acids, probably due to a cooperative activation of the carbon-oxygen bond. Thus the catalysis with Ir4(CO)i2 in a NaCl/AlCl3 melt converts at very reasonable rate carbon monoxide and hydrogen into light hydrocarbons, primarily ethane, without producing oxygenated compounds. [Pg.168]
