The word amphipolar characterizes the cyclic bonding interaction between alternately oppositely charged atoms that, for example, distinguishes the cyclotriphosphazenes from aromatic six‐membered ring compounds. An example is 1 (“1λ 5 ,3λ 5 ,5λ 5 ‐2λ 3 ‐tetraphosphabenzene”). It has now been synthesized by an new method incorporating a unique cascade of equivalent bond formation and cleavage reactions (PP, PC bonds).
