Bis[4-(trimethylsilyl)phenyl]diselenide (3) and bis[4-(trimethylsilyl)phenyl]disulfide (31) are found to be odorless equivalents of the commonly used diphenyl diselenide and diphenyl disulfide, respectively. The diselenide 3 is shown to be useful in the preparation of odorless selenium(II) chloride 26 and selenium(IV) trichloride 28 that follow similar reactivity patterns to their phenyl derivatives and can be stored refrigerated under dry conditions. The corresponding selenium(II) bromide had to be prepared fresh from 3 before use. It is also shown that the trimethylsilyl group in the sulfide products can be protodesilylated quantitatively using TFA.

无味二苯基二硒化物和二硫化物：合成与应用

双[4-(三甲基甲硅烷基)苯基]二硒化物(3)和双[4-(三甲基甲硅烷基)苯基]二硫化物(31)分别是常用的二苯基二硒化物和二苯基二硫化物的无味等效物。二硒化物 3 可用于制备无味的氯化硒 (II) 26 和三氯化硒 (IV) 28，它们的反应模式与其苯基衍生物相似，并且可以在干燥条件下冷藏储存。相应的溴化硒 (II) 必须在使用前从 3 新鲜制备。还表明硫化物产物中的三甲基甲硅烷基可以使用 TFA 定量地进行原甲硅烷基化。
