SYNTHESIS AND COMPLEXATION PROPERTIES OF A NOVEL POTASSIUM-SELECTIVE TRISANISYL BIS(BENZO-CROWN ETHER)

Abstract:

The condensation of 2,2′2″-trimethoxy-5,5′,5″- trimethyl-1,1′:3′,1″-terphenyl-3,3″-di(carbonyl chloride) (2) with two equivalents of 4-aminobenzo-15-crown-5 (15-amino-2,3,5,6,8,9,11,12-octahydro-1,4,7,10,13-benzopentaoxacyclopentadecine) (3) gave a novel bis(crown ether) (4) containing a rigid preorganised trisanisyl chain backbone. Titrations of this new host with alkali-metal cations and the ammonium ion monitored by 13C n.m.r. spectroscopy suggested that the benzo crown ether moieties alon...
