First representatives of resorcinol bis(cyclophosphites) were synthesized, on the basis of which a series of metallocomplexes, including a 16-membered binuclear metallocycle, was obtained. The fact that, in this system, two m-phenylene cycles are almost parallel with each other makes possible the creation of complex polynuclear constructions. The phosphocyclane rings in resorcinol bis(cyclophosphites) are readily opened by bromine and chloramine to form bis-(ω-halogenoallylphosphates) of resorcinol.
