A dual chalcogen-bonding interaction has been developed as a means of establishing conformational control in sulfur- and selenium-containing ureas. By virtue of this dual interaction, urea derivatives adopt a planar structure bearing an X⋅⋅⋅O⋅⋅⋅X arrangement (X=S, Se). The rigidity of the structure and the acidity were found to increase in the order benzothiophene
双硫族键相互作用已被开发为在含硫和含硒的脲中建立构象控制的一种手段。凭借这种双重相互作用,尿素衍生物采用具有 X⋅⋅⋅O⋅⋅⋅X 排列 (X=S, Se) 的平面结构。发现结构的刚性和酸度按照苯并噻吩<苯并硒吩脲的顺序增加。
