这项研究描述了制备硒衍生物(硒代二甘醇二酸二乙酯)的单一步骤,高收率和纯度,生态友好且可扩展的程序。亚硒酸二乙酯快速还原次氯酸(HOCl,二级速率常数为7×10 M s-1),生成相应的亚硒酸盐。在活化的HL-60细胞中,亚硒二酸二乙酯与HOCl(半数最大抑制浓度(IC50)= 23.07μM)选择性反应,但不与超氧化物阴离子自由基或过氧化氢反应,而没有任何细胞毒性。这些结果表明,这种合成上简单的硒化物以非常有效和特定的方式反应,有害的促氧化剂HOCl是一种有希望的化合物,可用于氧化性炎症相关疾病。

Photo-induced-electron transfer from triethylamine to phenylselenoalkanes can lead to selective reduction and cleavage of the PhSe bond leading to the formation of benzene and the corresponding alkyselenyl radicals that dimerize.
A variety of functionalised organodiselenides were prepared in excellent yields from the corresponding halides and activated alcohols on treatment with tetraethylammonium tetraselenotungstate 1 under very mild conditions. (C) 2003 Elsevier Science Ltd. All rights reserved.
