Synthesis and phosphorylation of 2,2',7,7'-tetra(phenylamino)-1,1'-binaphthalene

The reaction of 2,2',7,7'-tetrahydroxydinaphthylmethane with aniline in the presence of aniline salts involves the rupture of C–C bonds and the elimination of a methylene bridge and is completed by the formation of 2,2',7,7'-tetra(phenylamino)-1,1'-binaphthalene, the phosphorylation of which with 2-chloro-1,3,2-dioxaphosphinane and dichloroisopropyl phosphite yields original polycyclic phosphamide architectures.
