Spirocyclophosphazenes are formed when 1,8-dihydroxynaphthalene and a base react with (NPCl2)3 or 4 when 2,2′-dihydroxybiphenyl and base react with (NPCl2)4. However, catechol (1,2-dihydroxybenzene) and base interact with (NPCl2)4 to yield a phosphorane (II), rather than the spirophosphazene formed with (NPCl2)3. These differences are ascribed to the effects of ring strain when five-membered exocyclic rings are present.
