Synthesis and characterization of new symmetrical 3,6-bis[(25,26,27- tripropoxy-28-(3-(4-iodophenyl) propoxy)-p-tert-butyl calix[4]arene ethynyl]-9H-fluoren-9-one by Sonogashira coupling as a novel precursor for synthesis of quinodimethane (QDM)

Novel symmetrical 3,6-bis[(25,26,27-tripropoxy-28-(3-(4-iodophenyl)propoxy) -p-tert-butyl calix[4]arene ethynyl]-9H-fluoren-9-one with a cone conformation was synthesized by palladium-catalyzed coupling of (25,26,27-tripropoxy-28-(3- (4-iodophenyl)propoxy

Covalently linked at the lower rim double-calix[4]arene as a precursor for multicavity supramolecular receptor

New covalently linked at the lower rim double-calix[4]arens, which have great potential for the synthesis of multicavity receptors, were prepared via Sonogashira cross-coupling reaction. The structures of 6 and 7 were confirmed by NMR, MS, and elemental analysis. Copyright Taylor & Francis Group, LLC.
