radiospecific activity. 125I-Labeled dimethylaminoethyl iodophenoxyacetate derivatives (5a--e), dimethylaminoethyl iodophenoxyacetamide derivatives (7a--c), iodophenoxyethyl ethylenediamine derivatives (9,14) and an iodophenoxyethylpiperazine derivative (18) were efficiently synthesized from the corresponding aryltrimethylsilyl intermediates (4a--e, 6a--c, 8, 13, 17) by this method.
证明了通过芳基三甲基硅烷的脱金属进行放射性碘化的有用性。发现放射性碘化反应非常快,并且放射性碘的区域特异性掺入可以以高放射化学产率和高放射性比活度进行。从相应的芳基三甲基甲硅烷基中间体(4a-- e,6a--c,8,13,17)。
