Abstract |
: |
Iron catalysis has become an important topic in catalysis in the last decade.1 Iron
complexes are cheap, easily available, and most often relatively less toxic.
Traditionally, iron has been used as Lewis acid catalyst in homogeneous catalysis or
as catalyst or support in heterogeneous catalysis, which was usually performed at high
temperature or pressure. However, more recently an increasing number of ironcatalyzed
reactions, which precede under milder reaction conditions, have been
reported. Among the different iron complexes, iron oxides have been often considered
to be inactive under mild reaction conditions. However, some of them can be used as
magnetically separable support.
Recently, we have shown that nano-iron oxide is an active and selective catalyst
for alcohol and olefin oxidations to yield the corresponding aldehydes.2 Here, the
application of nano-iron oxide in oxidation and dehydrogenation of alcohols will be
presented for the first time (Scheme 1 a, b). In addition, the preparation of nano-iron
oxide supported nano-noble metal catalysts and their catalytic activity in fine
chemical synthesis, i.e. coupling of primary alcohol and sulfonamides, Scheme 1c,
will be also discussed. |
