我们报道了一种新的标记芳香族化合物的新方法,它使用无载体的短半衰期放射性氯离子([38,39Cl]Cl−和[34mCl]Cl−)和Oxone®(日本Sigma-Aldrich)作为氧化剂。在氧酮存在下,放射性氯离子与苯甲醚反应生成对氯苯甲醚和邻氯苯甲醚的混合物,在10 min内放化转化率大于85%(未经衰变校正),选择性为7:3。三丁基锡化合物经去氯化反应得到相应的放射性氯化物(对氯苯甲醚和间氯苯甲醚),放化产率分别为80%~95%和46%~65%。版权所有©2012 John Wiley&Sons,Ltd.
We report a novel labeling method for the rapid radiochlorination of aromatic compounds using no-carrier-added short-half-life radioactive chloride ions ([38,39Cl]Cl− and [34mCl]Cl−) and OXONE® (Sigma-Aldrich, Japan) as an oxidation reagent. The reaction of radioactive chloride ions with anisole in the presence of OXONE gave a mixture of p-[*Cl]chloroanisole and o-[*Cl]-chloroanisole, with a radiochemical conversion yield of more than 85% (not decay corrected) and selectivity of 7:3, within 10 min. Regioselective radioactive chlorination was achieved by chlorodestannylation of tributylstannyl compounds to afford the corresponding radiochlorinated compounds (p-chloroanisole and m-chloroanisole) in satisfactory radiochemical yields (80–95% and 46–65%, respectively).
