The invention relates to a process for producing a labelled compound, which process comprises treating a compound of formula (I), wherein X is a moiety to be labelled or a detectable label, and R1, R2, R3 and R4 are substitutent groups as defined herein; with a compound of formula (II) : N3-L-Y (π) wherein Y is a detectable label or a moiety to be labelled, provided that if X in the compound of formula (I) is a moiety to be labelled, then Y is a detectable label and if X in the compound of formula (I) is a detectable label, then Y is a moiety to be labelled; and L is a bond or a linking group, thereby producing a labelled compound of formula (IH) by Staudinger Ligation. Groups R3 and R4 may comprise fluorous moieties, in order to facilitate purification of the labelled compound of formula (IH). The invention also provides methods of imaging a human or non-human patient or a cell or in vitro sample, using the labelled compound of formula (III) thus produced, as well as imaging methods in which the compounds of formulae (I) and (II) are administered to the patient, cell or sample. The invention further provides novel compounds of formula (I) and formula (III), a process for producing the compounds of formula (T), and a combination product for medical imaging comprising a compound of formula (I) and a compound of formula (II).

The Staudingerligation of phosphine-substituted thioesters with 18F-fluoroethylazide has been successfully applied to access 18F-labelled molecules in radiochemical yields superior to 95%; the first fluorous variant of a Staudinger radio-ligation has been validated.

The synthesis of three pairs of orthogonally labelled fluorinated Cu bis(thiosemicarbazonato) complexes is presented. These are the first examples of 18F-labelled Cu(II)-complexes designed to serve as new hypoxia selective PET tracers and as mechanistic probes to study the mode of action of this class of markers. In vitro evaluation revealed that the fluorinated Cu-complex derived from amide coupling is suitable for in vivo work.

Tag team: The fluoro‐detagging of fluorous sulfonates by the [18F]fluoride ion was found to be an advantageous strategy for the preparation of various 18F‐labeled prosthetic groups and known radiotracers (see picture). Fluorous solid phase extraction (FSPE) was used to separate the excess fluorous precursor from the labeled material, which suggests that traditional purification protocols such as distillation
