出乎意料的是,亚硝酸钠在冰醋酸AcOH中将5,7-二烷基-3-硫代过氧氢杂咪唑[4,5- e ] -1,2,4-三嗪-6-酮(硫酮)亚硝化导致3,3'-bis(自发分解的5,7-二烷基-1-亚硝基-6-氧代(硫代)-1,4,4a,5,7,7a-六氢咪唑[4,5-e] -1,1,2,4-三嗪基)二硫化物在水存在下,在DMSO-d 6中转化为1,3-二烷基-5-硫代六氢咪唑并[4,5- d ]咪唑-2(1 H)-ones(thiones)。
Semithiobambusurils, which represent a newfamily of macrocyclic host molecules, have been prepared by a convenient, scalable synthesis. These newcavitands are double functional: they strongly bind a broad variety of anions in their interiors and metal ions at their sulfur‐edged portals. The solid‐state structure of semithiobambus[4]uril with HgCl2 demonstrates the ability of these compounds to form
