Sir Geoffrey Wilkinson was an English chemist and educator who was jointly awarded the ‘Nobel Prize in Chemistry’ in 1973 along with German chemist Ernst Otto Fischer for their independent but related pioneering work in metallocenes and other aspects in the field of organometallic chemistry. Through his investigations on the products of atomic fission reactions he was able to discover several new isotopes. He successfully deduced the structure of the newly developed synthesized compound which was called dicyclopentadienyl iron (at present called ferrocene) and displayed that the compound is composed of two carbon rings each of five sides, bound on opposite sides of an iron atom thus forming an organometallic molecule. He carried on with his research in this field and synthesized many other organometallic compounds, also known as ‘sandwich compounds’. The study of metal-to-hydrogen bonding by Wilkinson, especially the discovery of his homogeneous hydrogenation catalyst for alkenes, known as the Wilkinson's Catalyst composed of a rhodium metal complex with the metal center being linked to three large phosphine ligands proved to be of great significance in the field of organic and inorganic chemistry and play a vital role in industrial applications. He worked at the ‘Atomic Energy Project’ in Canada and taught at the ‘Harvard University’, ‘University of California’ at Berkeley, ‘Massachusetts Institute of Technology’ and ‘Imperial College, London. Apart from ‘Nobel Prize’, he received several awards including ‘ACS Award in Inorganic Chemistry’ (1965), the ‘Royal Medal’ (1981) and the ‘Davy Medal’ (1996) among others. In 1965 he was elected a ‘Fellow of the Royal Society’ (FRS) and in 1976 he was honored with the title of Knight.
He joined Professor Friedrich Paneth, an Austria-born British chemist, in late 1942 when the latter was recruiting young chemists for the Atomic Energy Project. In January 1943 he was sent to Canada where he worked on the Atomic Energy Project first at the ‘Université de Montréal’ in Montreal and then in the ‘Chalk River Laboratories’ in Deep River, Renfrew County, Ontario. He worked in this project till 1946 which included the war-time atomic research program of UK, the Tube Alloys nuclear project.
Post war in 1946 he applied and was accepted by Professor Glenn T. Seaborg, a noted American chemist, at the ‘University of California’, Berkley where he remained a scholar in nuclear chemistry till 1950. There he mostly remained occupied working on nuclear taxonomy. He applied a type of particle accelerator called cyclotron of the Radiation Laboratory and made several deficient isotopes. According to Professor Seaborg the artificial isotopes that were made by Wilkinson, around eighty nine, were more than any other person.
In 1950 he joined ‘Massachusetts Institute of Technology’ as a Research Associate. There he focussed his research work on his original interest that he had since his student life, transition metal complexes of ligands like olefins and carbon monoxide.
His nuclear background landed him a job at the ‘Harvard University from September 1951 to December 1955 as an Assistant Professor. While he began his research on olefin complexes, he also carried on with a few nuclear researches on excitation functions for protons in cobalt.
A publication of early 1952 regarding a newly developed synthesized compound called dicyclopentadienyl iron (at present called ferrocene) aroused his interest. He endeavoured and successfully deduced the structure of the synthesized compound and showed that it is composed of two carbon rings each of five sides, bound on opposite sides of an iron atom thus forming an organometallic molecule. Moving ahead he conducted further research in this field and synthesized many other organometallic compounds.
He took a sabbatical of nine months when he worked at Professor Jannik Bjerrum's laboratory in Copenhagen as a John Simon Guggenheim Fellow.
He was appointed by the ‘Imperial College’, London, to the chair of Inorganic Chemistry in June 1955, a position he took up in January 1956 and served for over three decades. There he mostly dedicated his research on complexes of transition metals and focussed his interest on complex chemistry of rhenium, rhodium and ruthenium and in compounds of unsaturated hydrocarbons among others. In 1988 he became professor emeritus.
His study of the metal-to-hydrogen bonding led him develop homogeneous hydrogenation catalyst for alkenes, chlorotris (triphenylphosphine) rhodium(I), a coordination compound with chemical formula RhCl(PPh3)3 (where Ph stands for phenyl), also referred as Wilkinson's Catalyst. It is composed of a rhodium metal complex with the metal center being linked to three large phosphine ligands.
He continued to work as emeritus professor in the ‘Imperial College’, London in the lab built for him by the firm ‘Johnson Matthey’.
He penned down many textbooks with his former doctoral student F. Albert Cotton, which included ‘Basic Inorganic Chemistry’ (1955), ‘Advanced Inorganic Chemistry’ (1962) and ‘Chemistry: An Investigative Approach’ (1970). In 1987 the ‘Pergamon Press’ published the 1st edition of ‘Comprehensive Coordination Chemistry: The Synthesis, Reactions, Properties & Applications of Coordination Compounds’ with Wilkinson, Jon A. McCleverty and Robert D. Gillard as contributors.
He was born on July 14, 1921, in a village called Springside, located near Todmorden, in the West Riding of Yorkshire to Harold Wilkinson and his wife Ruth Crowther as their eldest child among three.
His grandfather, who migrated from Boroughbridge to Yorkshire in around 1880 and his father were master house painters and decorators. His mother was a weaver who worked in local cotton mills.
In-laws of his eldest maternal uncle were owners of a small chemical company who made Epsom and Glauber's salts for the pharmaceutical industry. It was through his uncle, whom he accompanied on several visits to chemical companies, he developed interest in the field of chemistry.
He began his studies in the local council primary school and after receiving a County Scholarship in 1932, he joined the ‘Todmorden High School’, a comprehensive school located in the town of Todmorden in West Yorkshire.
Although a small school, it held an amazing record of academic achievements and produced 2 Nobel Laureates in a span of 25 years. He came under the guidance of the physics teacher who also taught Sir John Cockroft, a noted English Physicist, however Wilkinson never showed much interest in the subject.
He obtained a Royal Scholarship to study at the ‘Imperial College’, London in 1939 and earned a BS in Chemistry in 1941 at a time when the ‘Second World War’ was in full swing. As many strategically significant scientific research works were being conducted during wartime, he was instructed to carry on with some research work with Professor H.V.A. Briscoe as his supervisor.
He married Lise Solver, a physiologist in 1952. The couple was blessed with two daughters, Anne and Pernille.
On September 26, 1996, he succumbed to a heart attack in London, England at the age of 75.
He jointly received the ‘Nobel Prize in Chemistry’ in 1973 with German chemist Ernst Otto Fischer.
The ‘University of Bath’ conferred upon him an honorary doctorate of science in 1980.
Wilkinson remained member, foreign member and associate of many prestigious organisations. He was a foreign member of ‘Royal Danish Academy of Sciences’ (1968), ‘American Academy of Arts and Sciences’ (1970) and ‘American Chemical Society’ (1976) and a Foreign Associate of ‘National Academy of Sciences’ (1975).
