Contributions to coordination chemistry

Modified rhodium systems show considerable activity in the hydroformylation of styrene to the branched aldehydes. Chiral diphosphines, diphosphites, and phosphine-phosphites have been the ligands most studied. Hydroformylation experiments have often been performed in situ but the characterization of intermediates has provided an interesting contribution to coordination chemistry.179... 

In 1996, Coordination Chemistry Reviews (CCR) dedicated one of its issues to the memory of Joseph Chatt. I published an article in that issue entitled, Recollections of early studies on platinum(ii) complexes related to Chatt s contributions to coordination chemistry . For this reason, and because some authors will discuss platinum(ii) chemistry in other chapters, I will devote most of this paper to our research on the kinetics and mechanisms of platinum(ii) ligand displacement, and to the chemistry of platinum(iv) complexes. Since Joseph did little research on platinum(iv) chemistry, it seems appropriate that I review our work on it. Following this, I will briefly describe another area we worked on that interested Chatt although he was not involved in such research. This was that of making use of reaction mechanisms to help design the synthesis of metal complexes. 

The insight Werner provided into the bonding in coordination compounds is even more remarkable when we realize that his theory predated Lewis s ideas of covalent bonding by more than 20 years Because of his tremendous contributions to coordination chemistry, Werner was awarded the 1913 Nobel Prize in Chemistry. 

The Mossbauer effect was discovered in 1958 by Rudolf L. Mossbauer who received the Nobel Prize in physics for its discovery in 1961. Over the past 45 years the Mossbauer effect has developed into a well-established spectroscopic technique which has widely contributed " to coordination chemistry, inorganic and bioinorganic chemistry, and materials science. 

The so-called video salts (salts of the cw-[CoCl2(NH3)4] ion), which played a key role in Alfred Werner s coordination theory, were first prepared in 1907 by the Czech chemist J. V. Dubsky (1882-1946), who began his career in 1904 as one of Werner s Doktoranden in Zurich. The first attempt to resolve an octahedral complex into enantiomers is also connected with Dubsky s name. Dubsky s life and work, especially his contributions to coordination chemistry, are briefly discussed in this paper. 

John was the first recipient of the University of Illinois John C. Bailar, Jr. Medal, named in his honor, and his alma mater, the University of Michigan, named him Distinguished Alumnus for 1967. In recognition of his inestimable contributions to coordination chemistry, the Schweizerische Chemische Gesellschaft in Zurich, on September 3, 1966, at the centennial celebration of Alfred Werner s birth (IXICCC), presented John with the only Werner Gold Medal ever to be awarded, a fitting tribute to the elder statesman and prime mover of American coordination chemistry (16). 

Here I shall discuss only Jensen s contributions to coordination chemistry. However, from about 1938 his research gradually moved more and more into organic chemistry. For generations Jensen was one of the most infiuential Danish chemists. He was a splencfid lecturer and wrote a successful system of textbooks (5, d).
