The synthesis of hydroxyl silylated thiols as monodentate ligands is described. These monodentates were used to build with Re and 99mTc trimethyl-, triethyl- and triphenyl-silylated ‘3+1’ mixed ligand complexes, using 3thiapentane-1,5-dithiol as co-ligand. The Re complexes were characterized by 1H NMR and elemental analysis, the 99mTc complexes were detected by radio HPLC. While the trimethyl silylated derivatives hydrolysed in aqueous media, the triethyl- and triphenyl silylated complexes have proved to be stable in neutral solutions.

本文介绍了羟基硅烷化硫醇作为单齿配体的合成过程。以 3thiapentane-1,5-dithiol 作为辅助配体,这些单齿配体被用于与 Re 和 99mTc 三甲基、三乙基和三苯基硅烷化 "3+1 "混合配体复合物的构建。Re 复合物通过 1H NMR 和元素分析进行表征,99mTc 复合物通过无线电 HPLC 进行检测。三甲基硅烷基化衍生物在水介质中会水解,而三乙基和三苯基硅烷基化复合物在中性溶液中证明是稳定的。Copyright © 2002 John Wiley & Sons, Ltd. All Rights Reserved.
