[18F]Fluorination of o-carborane via nucleophilic substitution: towards a versatile platform for the preparation of 18F-labelled BNCT drug candidates†
Abstract
The mono-[18F]fluorination of o-carborane via nucleophilic substitution is reported. The new radiochemical transformation uses cyclotron produced [18F]F− and a carboranyl iodonium salt. Further derivatization of the 18F-labelled carborane is achieved by formation of the Cc-lithio salt and reaction with an aldehyde.
