The Chemistry of Ruthenium Oxidation Complexes

This chapter is essentially a review of those ruthenium complexes which have been used as oxidation catalysts for organic substrates, emphasis being placed on such species which have been chemically well-defined and are effective catalysts. Of all the ruthenium oxidants dealt with here those which have the greatest diversity of use are RuO, [RuO ] , [RuO ], the tetramesityl porphyrinato (TMP) complex fran.y-Ru(0)2(TMP), RuCl3(PPh3)3, and cw-RuCl3(dmso). Many other catalysts are covered, and the uses of two principal starting materials, RuO. nH O and RuClj. nH O as precursors for a number of catalysts, discussed.

In general ligands are listed in order of increasing denticity within a complex, e.g. [RnCHpXbpyXtpy)] rather than [Rn(tpy)(H20)(bpy)] . 

Starting Ru material/co-oxidant/solvent/temperature (if not ambient) is used. Thus Fig. 1.1 would be written in the text as RuO /aq. Na(IO ), meaning that RuO is generated in situ from RuOj.nH O and aqueous sodium periodate (only nonambient temperatures would appear in the rubric). Biphasic solvent mixtures with water are denoted as water-solvent. 

In a work of this length the use of abbreviations is essential. If an abbreviation is used in one paragraph only (as is the case for some complex ligands) it is defined in that paragraph alone.
