Platinum group metals chemistry

There are several exceUent sources of information about the platinum-group metals. The exceUent reference work G. Wilkinson, R. D. GiUard, and J. A. McCleverty, eds.. Comprehensive Coordination Chemistry Pergamon Press, Oxford, U.K., 1987, contains iadividual chapters devoted to descriptive chemistry of each element. 

Two works provide exceUent coUections of articles describiag important modem appfications of PGMs. These are E. H. Hardey, ed.. The Chemistry of Platinum Group Metals, Elsevier, 1991, and Gmelin Handbook of Inorganic Chemistry Platinum Suppl Vol. Al, Sptinger-Vedag, New York, 1986.

In the realm of C-H bond transformations applied toward the synthesis of fine chemicals, iridium has not achieved the prominence attained in recent years by the second-row platinum group metals, particularly palladium [10]. A notable exception, however, has been the leading role of iridium in the valuable chemistry of arene borylation [11].

Palladium(IV) is a relatively rare oxidation state. The paucity of isolated complexes in comparison with PtIV has been ascribed to the much higher ionization potential required to produce Pd4+ (109.5 us. 97.16 eV for PtIV).303 Binary complexes with oxide and the chal-cogenides have been well characterized as have PdF4 and [PdXe]2- (X = F, Cl, Br). The chemistry of platinum group metals in higher oxidation states has been the subject of a recent review.304... 

The coordination chemistry of sulfoxides with transition metals is a much-studied topic.87 Academic interest has often centred on their ambidentate donor ability, while dimethyl sulfoxide (DMSO) is of intrinsic importance as one of the most effective aprotic solvents known. Higher sulfoxides have found application in the extraction of metals during refining processes and some potential in the separation of platinum group metals has been noted.88...

Even with these limitations, nuclear magnetic resonance has made significant contributions to four areas of the chemistry of the platinum group metals bonding problems, molecular stereochemistry, solvation and solvent effects, and dynamic systems—reaction rates. Selected examples in each of these areas are discussed in turn. Because of space limitations, this review is not meant to be comprehensive. 

Each category, by itself, can be a topic for a separate symposium, and it is hoped that in the future such symposia will be forthcoming. The topics chosen were such that they would cover a broad area of the chemistry of platinum group metals. The session on industrial aspects was included to enable scientists in industry to present their views on the problems that are facing the industry and perhaps stimulate sufficient interest so that newer applications could be developed in the future. It is also hoped that such a forum would enable scientists in industry to summarize broadly the work carried out by them without worry about violation of proprietary nature of the work.

Fig. 8.3 Warren R. Roper (born in 1938) studied chemistry at the University of Canterbury in Christchurch, New Zealand, and completed his Ph.D. in 1963 under the supervision of Cuthbert J. Wilkins. He then undertook postdoctoral research with James P. Collman at the University of North Carolina at Chapel Hill in the US, and returned to New Zealand as Lecturer in Chemistry at the University of Auckland in 1966. In 1984, he was appointed Professor of Chemistry at the University of Auckland and became Research Professor of Chemistry at the same institution in 1999. His research interests are widespread with the emphasis on synthetic and structural inorganic and organometallic chemistry. Special topics have been low oxidation state platinum group metal complexes, oxidative addition reactions, migratory insertion reactions, metal-carbon multiple bonds, metallabenzenoids and more recently compounds with bonds between platinum group metals and the main group elements boron, silicon, and tin. His achievements were recognized by the Royal Society of Chemistry through the Organometallic Chemistry Award and the Centenary Lectureship. He was elected a Fellow of the Royal Society of New Zealand and of the Royal Society London, and was awarded the degree Doctor of Science (honoris causa) by the University of Canterbury in 1999 (photo by courtesy from W.
