A convenient method of synthesis of phosphoryl-substituted podands with dipehnylphosphorylmethyl end groups of the general formula Ph2P(O)CH2O(CH2CH2O)nCH2P(O)Ph2 (Ln, n = 0–6) is described. The stability constants of the complexes of the podands with alkali metal 2,4-dinitrophenolates were determined by conductometry. The ion-selective properties of the podands with respect to alkali and alkaline-earth
一种合成具有通式Ph 2 P(O)CH 2 O(CH 2 CH 2 O)n CH 2 P(O)Ph 2(L n,n = 0的二戊基磷酰基甲基端基的磷酰基取代的Podands的简便方法–6)描述。通过电导法测定豆荚与碱金属2,4-二硝基苯酚盐的配合物的稳定性常数。通过离子测定法评估了荚果对碱金属和碱土金属阳离子的离子选择性。通过X射线衍射分析确定了1,3-双(二苯基磷酰基)-2-氧丙烷的晶体结构。
