Abstract
A method for the preparation of sodium (^11^C]thiocyanate from [^11^C]cyanogen bromide and sodium sulfide is described. Sodium [^11^C]thiocyanate was obtained in 94% decay‐corrected radiochemical yield with a specific radioactivity of 122 GBq μmol^−1^ (3.3 Ci μmol^−1^) in a synthesis time of 21 minutes. The sodium [^11^C]thiocyanate was used in the synthesis of ethyl‐, isopropyl‐, and benzyl [^11^C]thiocyanate in 78, 71 and 84% radiochemical yields, respectively.
