The anion binding ability of a family of bis‐selenoureas L1 ‐L3 obtained by the reaction of 1,3‐bis(aminomethyl)‐benzene and phenylisoselenocyanate, p ‐methoxyphenylisoselenocyanate and naphtylisoselenocyanate, for L1 , L2 , and L3 , respectively, has been tested and compared to that of previously described bis‐urea analogues. Results suggest that the introduction of selenium leads to an increase in
一个家庭的阴离子结合能力双selenoureas L1 - L3由1,3-双(
氨基甲基) -苯和phenylisoselenocyanate,反应得到p -methoxyphenylisoselenocyanate和naphtylisoselenocyanate,为L1,
L2,和L3,分别,一直测试并与先前描述的双
脲类似物进行比较。结果表明,
硒的引入导致
尿素NH氢原子的酸度增加,因此对
DMSO- d 6中的阴离子种类,特别是
磷酸二氢盐具有更强的亲和力(高三倍以上)。。理论计算可以优化加合物受体,从而证实了实验结果。
