Robert H. Crabtree is a British organometallic chemist renowned for his contributions to homogeneous catalysis, particularly the development of what is commonly known as “Crabtree’s catalyst,” a cationic iridium complex used for selective hydrogenation reactions.
Early life and education
- Born in 1948 in the United Kingdom.
- Earned his undergraduate degree in chemistry at the University of Oxford.
- Completed a DPhil (Ph.D.) at Oxford under the supervision of Malcolm Green, focusing on transition‑metal organometallic chemistry.
Academic and research career
- Began his academic career as a lecturer and later senior lecturer at the University of Oxford.
- In 1992, he accepted a professorship at the Swiss Federal Institute of Technology (ETH Zurich), where he led a research group in the Department of Chemistry.
- Retired from active teaching duties in 2015 and holds the title of Professor Emeritus at ETH Zurich.
Research contributions
- Crabtree’s catalyst: Developed the cationic iridium(I) complex [(COD)Ir(ethylene)(py)]⁺ (where COD = 1,5‑cyclooctadiene, py = pyridine). This catalyst is notable for its high activity in the hydrogenation of olefins and alkynes under mild conditions and has been widely adopted in both academic and industrial settings.
- C–H activation: Pioneered strategies for the activation and functionalisation of carbon–hydrogen bonds using transition‑metal complexes, contributing to the broader field of selective organic synthesis.
- Hydrogen storage and spillover: Investigated mechanisms of hydrogen adsorption and storage on metal surfaces, informing the design of materials for energy applications.
- Authored several influential textbooks and review articles, including the widely cited monograph The Organometallic Chemistry of the Transition Metals (co‑edited with J. G. McMurray).
Awards and honours
- Elected Fellow of the Royal Society (FRS).
- Member of the European Academy of Sciences.
- Recipient of the Royal Society of Chemistry’s Award for Organometallic Chemistry (2002).
Professional service
- Served on editorial boards for journals such as Organometallics and Journal of the American Chemical Society.
- Acted as a reviewer and advisor for numerous international research funding agencies.
