Ammonium [(11)C]thiocyanate: revised preparation and reactivity studies of a versatile nucleophile for carbon-11 radiolabelling

Herein we report the preparation of ammonium [(11)C]thiocyanate via the reaction of [(11)C]CS(2) with ammonia. The [(11)C]SCN(–) ion is demonstrated as a potent nucleophile that can be used to readily generate a range of (11)C-labelled thiocyanate molecules in high conversions. Furthermore, novel (1...

Sumario:Herein we report the preparation of ammonium [(11)C]thiocyanate via the reaction of [(11)C]CS(2) with ammonia. The [(11)C]SCN(–) ion is demonstrated as a potent nucleophile that can be used to readily generate a range of (11)C-labelled thiocyanate molecules in high conversions. Furthermore, novel (11)C-labelled thiazolone molecules can be easily prepared from the intermediate α-thiocyanatophenones via an acid mediated cyclisation reaction.
