APPLICATIONS OF POLYOXOMETALATES IN HOMOGENEOUS CATALYSIS

摘要

This chapter will present an overview on the use of polyoxometalates as catalysts in homogeneous reaction media. This is not meant to be a comprehensive review as several such reviews are already available covering material up to the last few years, but rather an attempt to describe, also to non-practitioners, the general principles involved in this important field of application of polyoxometalate chemistry. This chapter will cover first more briefly the use of polyoxometalates as acid catalysts and then the use of polyoxometalates in oxidation catalysis. The discussion of oxidation catalysis will emphasize both general principles involved in the activation of oxidants and oxygen donors and the specific use of polyoxometalates in this context. Emphasis will be on oxidative transformations involving hydrocarbons and much of the description and discussion will be concentrated on research carried out in our group (my apologies in advance to those whose research was not completely covered).
