Phthalocyanine super-complex

The lanthanide phthalocyanine complexes, obtained by conventional methods starting from metal salts at 170-290°C and phthalonitrile (Example 26), contain one or two macrocycles for each metal atom [5,6,8,63,82,84-98]. Thus, according to Refs. 6,63, and 85, the complexes having compositions LnPc2H, XLnPc (X- is halide anion), and Ln2Pc3 (a super-complex ) were prepared from phthalonitrile as a precursor the ratio of the reaction products depends on the synthesis conditions and the metal nature. The ionic structure Nd(Pc)+Nd(Pc)2 was suggested [85] and refuted [63] for the neodymium super-complex Nd2Pc3 the covalent character of the donor-acceptor bonds in this compound and other lanthanide triple-decker phthalocyanines was proved by the study of dissociation conditions of these compounds [63]. 

The lanthanide phthalocyanines (Fig. 5.2) can also be obtained from the corresponding metal salts and metal-free phthalocyanine or 1,3-D [6], It has been established [6,86] that whereas a diphthalocyanine complex Pc2LnH is mainly obtained for the heaviest lanthanides (Dy-Lu), a super-complex Pc3Ln2 is progressively... 

Template reactions of 1,2-dicyanobenzenes with uranyl salts lead to the synthesis of super-phthalocyanines (Scheme 54).237,23s jjjg uranyl ion can be displaced from the macrocycle by a range of metal salts, but a ring contraction occurs to yield normal phthalocyanine complexes (Scheme... 

A more recent focus of attention has been the oxidation reactions with O2 in the presence of so-called enzyme mimics [15, 58 - 71]. The most recent discoveries in connection with the selective partial oxidation of nonactivated alkanes over metal phthalocyanine complexes (MPc) enclosed in faujasite super-cages are very promising and many potential applications for these inorganic simulations of enzymes, for example of the natural monoxygenase enzyme cytochrome P 450 are possible.
