Prof. Bengt Långström is a pioneer in the field of chemistry‐driven positron emission tomography (PET) imaging. He has developed a variety of excellent radiolabeling methodologies using the methods of organic chemistry, with the aim of widening the potential of PET in the study of life. Among his groundbreaking achievements in 11 C radiochemistry, there is the discovery of the Pd‐mediated rapid cross‐coupling reaction using [ 11 C]methyl iodide. It was first reported by his Uppsala group in 1994–1995 and was further investigated by his and other groups with a view of enhancing its generality and practicability. This reaction is currently considered one of the basic methods for 11 C‐labeling of low‐weight organic compounds. This paper presents a short summary of the background and the development of Pd‐mediated rapid cross‐couplings of [ 11 C]methyl iodide, with a focus not only on organostannanes, but also on organoboranes, organozincs, and terminal acetylene compounds. All these reactions have proven to be dependable 11 C‐labeling methodologies that use chemically reliable carbon–carbon bond formation reactions.
