Reaction of the manganese tropocoronand complex [Mn(tc-5,5)(NO)] with [Fe(tc-5,5)] results in complete transfer of the NO to the [Fe(tc-5,5)]. Other nitric oxide complexes appear in the sections on nitroprusside (Section S.4.2.2.6 above), on phthalocyanines (Section 5.4.3.7.4 above), and on polynuclear iron-sulfide complexes (Roussin s salts Section 5.4.5.9.2 below) Fe-por-phyrin-NO redox chemistry has been mentioned in Section 5.4.3.7.2 above.

Abstract This chapter discusses the electronic absorption spectra and electrochemistry of phthalocyanine complexes which are redshifted to 730nm and beyond. These are mainly manganese phthalocyanine derivatives and phthalocya-nines containing sulfur substituents. The chapter concentrates mainly on the work done during the last 10 years. There are 96 references quoted and three detailed tables on the electronic absorption spectra, redox potentials, and analytes that are electrocatalyzed using manganese and titanium phthalocyanine complexes.

In addition there has been a recent review of manganese porphyrin chemistry (19) as well as of the aqueous and chloro complexes of the porphyrin species (20). These discussions are complemented by a discussion of the electrochemistry of manganese porphyrin compounds (21). Related studies include the phthalocyanine complexes (22), the manganese (III)-hemoglobin structure (23), and the characterization of macrocyclic complexes of manganese (24, 25). Other relevant chemistry involves the Schiff-base complexes of Mn(III) (26, 27, 28). 

The phthalocyanine complexes of manganese have been studied for many years ° The most recent work has established the formation of an rf dioxygen complex on oxygenation of [Mn(Pc)] in N,N-dimethylacetamide solution and a similar result has been obtained for a tetra-sulphonated phthalocyanine derivative The porphyrin complex Mn(TPP)02 was assigned an rf structure on the basis of E.P.R. data and this assignment has recently been supported by infra-red data using 02 Schiff base complexes of Mn(II) were reported to form dinuclear rf complexes on oxygenation in... 

Recent reviews of the phthalocyanines by Lever (57) and by Moser and Thomas 66) are available. Complexes of phthalocyanine with all of the first row transition elements, excepting scandium, have been prepared. However, titanium and vanadium phthalocyanines are known only as the oxy- or chloro-compounds and are not then strictly square planar. That phthalocyanine has considerable ability to promote the square planar configuration is further demonstrated by the existence of the chromium (III) and manganese(II) complexes (57).

The applications reported for polymer-supported, soluble oxidation catalysts are the use of poly(vinylbenzyl)trimethylammonium chloride for the autooxidation of 2,6-di-tert-butylphenol [8], of copper polyaniline nanocomposites for the Wacker oxidation reaction [9], of cationic polymers containing cobalt(II) phthalocyanate for the autooxidation of 2-mercaptoethanol [10] and oxidation of olefins [11], of polymer-bound phthalocyanines for oxidative decomposition of polychlorophenols [12], and of a norbornene-based polymer with polymer-fixed manganese(IV) complexes for the catalytic oxidation of alkanes [13], Noncatalytic processes can also be found, such as the use of soluble polystyrene-based sulfoxide reagents for Swern oxidation [14], The reactions listed above will be described in more detail in the following paragraphs. 

Phthalocyanine complexes of cobalt(II), copper(II), manganese(11), and iron(II) catalyze the oxidation of substituted phenols to the corresponding benzoquinones and diphenoquinones. Typical selectivity data are listed in Table III.
