Abstract

original image

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 (“1λ5,3λ5,5λ5-2λ3-tetraphosphabenzene”). It has now been synthesized by an new method incorporating a unique cascade of equivalent bond formation and cleavage reactions (P[BOND]P, P[BOND]C bonds).
