Abstract

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.
