Abstract of Disclosure Described herein are novel macrocyclic compounds capable of complexing cations, and the complexes so obtained. The novel macrocyclic compounds are monocyclic or bicyclic compounds, and specified derivatives thereof, represented by the formula Image wherein each R1 is hydrogen, a hydrocarbon group or an alkoxycarbonyl group, or both R1 form together a grouping of the general formula Image (i.e. providing a third bridge between the two X- groupings in the molecule); each A is a hydrocarbon group; each X is nitrogen or phosphorus; each D is oxygen, sulfur, ?N-R (R being hydrogen or a hydrocarbon group) or a hydrocarbon group, with the proviso that, at least two of the groups or atoms represented by D are selected from oxygen, sulfur and ?N-R, and that when each R1 is hydrogen, hydrocarbon or alkoxycarbonyl and X is nitrogen, then one of these two groups or atoms represented by D is oxygen or sulfur and the other is oxygen or ?N-R; and m, n and p are integers from 0 to 5. The preparation of the novel compounds by bridge form- ation between the X groups is described. The compounds of the above formula are very strong complexing agents and are of value for use in much the same way and for the same purposes as chelating agents. The cation con- taining complexes of the compounds of this invention are equally useful in many fields such as, for example, as catalysts. - 2 -
