dioctyl-18S6, were synthesized starting from different dithiols and dihalides. Cs2CO3 is used for the cyclizations. The extraction behavior of palladium (II) from nitric acid media with these reagents in chloroform has been studied in terms of extraction equilibrium constants Kex. The influence of parameters such as lipophilicity brought by alkyl chains, macrocyclic cavity size and number of sulfur donor atoms
从不同的位置开始合成了六种新的亲脂性硫杂冠醚(– ),分别缩写为2-辛基-9S3、2-辛基-10S3、2-辛基-12S4、6-辛基-14S4、3-辛基-16S4和二辛基-18S6。二硫醇和二卤化物。Cs 2 CO 3用于环化。根据萃取平衡常数K ex,研究了这些试剂在氯仿中从硝酸介质中萃取钯(II)的行为。研究了烷基链带来的亲脂性,大环孔尺寸和硫给体原子数等参数对萃取行为的影响。
