The intrinsic ion-exchange properties of p-doped polymers have been used to bind electrocatalytic anions such as porphyrins238 and phthalocy-anines.239 Cation-substituted polymers have been used to bind anions such as [Fe(CN)6]3-/4-,235 oxometallates,240 and porphyrins241 and anion-substituted polymers have been used to bind a variety of cationic species such as [Co(2,2/-bipyridine)3]3+/2+)58 [Ru(NH3)6]3+/ 2+,183 and porphyrins.242... 

The validity of Eq. (31) has been confirmed by an approach from redox potentials of heteropoly oxometalate anions as well [59].

In recent years numerous papers have been published on the vibrational properties of oxometaUates. A short compilation of some of this data has been given in Refs. (32) and (33). Recently Gonzalez-Vilchez and Griffith (34) examined the infra-red and Raman spectra of a number of oxometallates. However, most of the values given there and the conclusions obtained from those values are not correct as we hope to demonstrate later. Various regularities as well as interdependences between spectroscopic behavior and other properties of these oxosubstances will be discussed [see also (35—37)). 

In 2003, Adam, Zhang and coworkers published a method for the asymmetric epoxi-dation of allylic alcohols catalyzed by an oxo-vanadium substituted sandwich-type poly-oxometalate (POM) 144 with TADOOH 60 as chiral oxygen source. Upon screening of a group of differently substituted POMs, [ZnWM2(ZnW9034)2] (M = OV(IV), Mn (II), Ru (in), Fe (III), Pd (II), Pt (II), Zn (II) q = 10-12] 144 turned out to be the most effective one (Scheme 66).
