Richard John Puddephatt, OC FRSC FCIC [3] was born 1943 in Aylesbury, England. [2] He is a distinguished university professor in the department of chemistry at the University of Western Ontario, in London, Ontario, Canada. Richard is a former holder of a Canada research chair in material synthesis. He has been studying the fundamental chemistry of gold and other precious metals in the development of new materials for potential applications in health care and electronics. [1] Puddephatt's research interests involve organometallic chemistry related to catalysis and materials science, [4] and he is considered a world expert on platinum and gold chemistry. [5] He has authored two books: The Chemistry of Gold and The Periodic Table of Elements. [6] [7]
Puddephatt has conducted research on synthesis, reactivity and elucidation of mechanisms in the organometallic chemistry of the noble metals, particularly related to the role of organometallic compounds in catalysis and in materials science. He has elucidated the mechanisms of reactions in many homogenous catalytic processes, foe instance in studies of oxidative addition and reductive elimination with alkylplatinum and alkyl–gold complexes and of skeletal rearrangements of metallacyclobutane complexes, often called the Puddephatt rearrangement. [3]
Coordinatively unsaturated platinum clusters and platinum–rhenium clusters have been synthesised and shown to be excellent mimics of the surface reactivity, related to heterogeneous catalysis by supported platinum and bimetallic platinum–rhenium catalysts. Commercially useful organometallic precursors for chemical vapour deposition (CVD) of thin films of metals such as palladium, platinum, silver and gold have been discovered and the mechanisms of those CVD processes elucidated. He has also synthesised catenanes and metal-containing polymers by dynamic ring opening polymerisation. [3]
Puddephatt was won numerous awards [4] including
Catalysis is the increase in rate of a chemical reaction due to an added substance known as a catalyst. Catalysts are not consumed by the reaction and remain unchanged after it. If the reaction is rapid and the catalyst recycles quickly, very small amounts of catalyst often suffice; mixing, surface area, and temperature are important factors in reaction rate. Catalysts generally react with one or more reactants to form intermediates that subsequently give the final reaction product, in the process of regenerating the catalyst.
Organometallic chemistry is the study of organometallic compounds, chemical compounds containing at least one chemical bond between a carbon atom of an organic molecule and a metal, including alkali, alkaline earth, and transition metals, and sometimes broadened to include metalloids like boron, silicon, and selenium, as well. Aside from bonds to organyl fragments or molecules, bonds to 'inorganic' carbon, like carbon monoxide, cyanide, or carbide, are generally considered to be organometallic as well. Some related compounds such as transition metal hydrides and metal phosphine complexes are often included in discussions of organometallic compounds, though strictly speaking, they are not necessarily organometallic. The related but distinct term "metalorganic compound" refers to metal-containing compounds lacking direct metal-carbon bonds but which contain organic ligands. Metal β-diketonates, alkoxides, dialkylamides, and metal phosphine complexes are representative members of this class. The field of organometallic chemistry combines aspects of traditional inorganic and organic chemistry.

Tobin Jay Marks is an inorganic chemistry Professor, the Vladimir N. Ipatieff Professor of Catalytic Chemistry, Professor of Material Science and Engineering, Professor of Chemical and Biological Engineering, and Professor of Applied Physics at Northwestern University in Evanston, Illinois. Among the themes of his research are synthetic organo-f-element and early-transition metal organometallic chemistry, polymer chemistry, materials chemistry, homogeneous and heterogeneous catalysis, molecule-based photonic materials, superconductivity, metal-organic chemical vapor deposition, and biological aspects of transition metal chemistry.
The Willard Gibbs Award, presented by the Chicago Section of the American Chemical Society, was established in 1910 by William A. Converse (1862–1940), a former Chairman and Secretary of the Chicago Section of the society and named for Professor Josiah Willard Gibbs (1839–1903) of Yale University. Gibbs, whose formulation of the Phase Rule founded a new science, is considered by many to be the only American-born scientist whose discoveries are as fundamental in nature as those of Newton and Galileo.
Organoplatinum chemistry is the chemistry of organometallic compounds containing a carbon to platinum chemical bond, and the study of platinum as a catalyst in organic reactions. Organoplatinum compounds exist in oxidation state 0 to IV, with oxidation state II most abundant. The general order in bond strength is Pt-C (sp) > Pt-O > Pt-N > Pt-C (sp3). Organoplatinum and organopalladium chemistry are similar, but organoplatinum compounds are more stable and therefore less useful as catalysts.
