1,3,5-Benzene-tri-p-phenylphosphonic acid. A new building block in supramolecular chemistry

Beckmann, Jens; Ruttinger, Roman; Schwich, Torsten


Benzene-1,3,5-tri-p-phenylphosphonic acid, 1,3,5-[p-C6H 4P(O)(OH)2]3C6H3, (8), a novel building block for applications in supramolecular chemistry, was prepared in two steps with an overall yield of 82%. The [Pd(PPh3) 4]-catalyzed Arbuzov reaction of 1,3,5-tris(p-bromophenyl)benzene with P(Oi-Pr)3 afforded benzene-1,3,5-tri-p-phenylphosphonic diisopropyl ester, 1,3,5-[p-C6H4P(O)(Oi-Pr) 2]3C6H3 (9). The hydrochloric acid-catalyzed hydrolysis of 9 produced 8, which forms a crystalline salt with...[Show more]
