aliphatic C-H bonds with no-carrier-added [(18)F]fluoride. The method uses Mn(salen)OTs as an F-transfer catalyst and enables the facile labeling of a variety of bioactive molecules and building blocks with radiochemical yields (RCY) ranging from 20% to 72% within 10 min without the need for preactivation of the labeling precursor. Notably, the catalyst itself can directly elute [(18)F]fluoride from an

Methods of direct radioactive labeling a carbon containing compound having an sp3 C-H bond are provided. Methods of carrier-free 18F fluorination of a carbon containing compound mediated by manganese salen complexes or manganese porphyrin complexes comprising weakly coordinated anions as axial ligands are provided. Methods of "dry-down" free radioactive labeling of a carbon containing compound having an sp3 C-H bond are provided. The radioactively labeled products of the methods are provided.
Methods of halogenating a carbon containing compound having an sp3 C—H bond are provided. Methods of fluorinating a carbon containing compound comprising halogenation with Cl or Br followed by nucleophilic substitution with F are provided. Methods of direct oxidative C—H fluorination of a carbon containing compound having an sp3 C—H bond are provided. The halogenated products of the methods are provided.
Methods of C—H bond fluorination using non-heme manganese catalyst are described herein. For example, a method comprises providing a reaction mixture including a non-heme manganese catalyst, a substrate comprising an sp3 C—H bond and a fluorinating agent and converting the sp3 C—H bond to a C—F bond in the presence of the non-heme manganese catalyst or a derivative thereof.
