Biomimetic chemistry
Several cases are described in which the chelate effect contributes to binding and catalysis. In the first examples, dimers made up of linked cyclodextrins show very strong selective substrate binding, and with catalytic groups in the linkers they are effective catalysts of reactions of bound substrates. In later examples, chelate binding of transition states by a base and an acid produce effec...

This chapter gives an overview on the chemistry of tetravalent lanthanide compounds, especially those of tetravalent cerium. Following a brief Introduction it covers the tetrahalides, dioxides and other lanthanides(IV) salts. Coordination compounds of cerium in the oxidation state +4 include halogeno complexes and complexes of oxo acids, β-diketonates and related Schiff-base complexes as well a...
