Iodine and bromine inclusion compounds were easily prepared by gas diffusion of the halogens using finely powdered CB[6]. A brown powder consisting of I2âCB[6]·4H2O and an orange one of (Br2)4âCB[6]·10H2O were employed in several different reactions. I2âCB[6] can be used in catalytic reactions giving yields comparable to those reported in the literature. Br2âCB[6] was effectively applied in electrophilic bromination of benzene and formation of bromohydrin. However, the radical substitution at cyclohexene could not be performed. Overall, based on these results, several applications can be envisioned for these complexes.
碘和
溴的包合化合物可以通过气体扩散法,使用细粉CB[6]轻松制备。我们使用了由I2–CB[6]·4H2O组成的棕色粉末和由(Br2)4–CB[6]·10H2O组成的橙色粉末进行多种不同的反应。I2–CB[6]可以用于催化反应,产率与文献中报告的相当。Br2–CB[6]在苯的亲电
溴化和
溴醇的形成中得到了有效应用。然而,在
环己烯上的自由基取代反应无法进行。总的来说,基于这些结果,可以设想这些复合物的多种应用。
